Why does a computer run slow?

Your computer is running slow for so many reasons but two of them has to do with your processor speed and RAM (Random Access Memory). These two things also are the main determinants of your PC price. Sometimes one is higher than the other, depending on your need. So, if you need the PC for gaming, most times, priority is placed on the Graphic card processor to process the game's FPS (frames per second), and then the ram is also needed). So both components are highly required for gaming. And depending on the type of game you want to play, if the required amount of RAM isn't reached for the Processor speed is low, the game might not even run, or the even if it does, it will lag a lot and cause the PC to heat up, and worse things can happen. On the other hand, if you need the pc for other things rather than gaming, priority is placed more on the RAM. The higher the RAM sized the more speed you get and it allows you have multiple programs open all at once on the PC. The Processor is not really given that much priority here unless maybe in case of graphic designing. So, having understood this, what other factors can cause your PC to become slow? 1. Unnecessary background programs running at startup which most times are from malware installed on your PC when you visited a website unprotected. 2. multiple programs opened simultaneously when you have a low size RAM. We must understand that a slow PC isn't always caused by viruses or other dangerous factors, but it depends on how we use our PC. If you are able to understand some basic PC maintenance skill, it will save you a lot of money from buying software that will help do that. How can you fix this? First, I recommend saving your important files and formatting your PC every 6 months. Always clear browser cache. Go to task manager, click on startup programs and disable programs with high impact from opening during PC startup. After doing this, your PC will be back to the speed force in no time. Most of all understand what your PC is meant for.

Why would your computer automatically restart after being turned off?

All Windows versions have the same function. From the Start button, select menu/programs/accessories/system tools/system information, then click on the tools menu and select system configuration utility.

When the program opens, you'll see an advanced button on the bottom right corner. Press it.

Make sure you have disabled fast shutdown (CHECKED). Press OK/OK. If it prompts for restart, don't do it, you don't need to. Press cancel on that screen and then shutdown like you would normally.

AnswerI have found I think the answer to that question, although I haven't had the time to test it since it is on a friends computer using xp pro. but you can if you like. go to the bios and check your modem if you are on a phone line and disable the auto start feature...You may find it only restarts when a call comes in... AnswerThe bios settings turn the computer on automatically. I actually have mine set to turn on automatically in the morning before I get out of bed so it's already on when I get up.

Watch what you see on your screen as you boot up the computer and do whatever it tells you to do to boot up in bios (typically by hitting the F2 or Del key). Once in bios, go to the power section. In the power setting you should see something pertaining to the modem. If you do NOT want it to power up automatically, choose the Disable option.

If you DO want to power it up automatically, it will also ask for a time (day of month, hour, minute). If you set the day as 1, for example, it will power up on the 1st of the month at the time that is set. If you set the day of the month to zero (0), it will power up every day at that time.

AnswerTry turning off the hibernation feature that can be found through control panel->display->screensaver tab->power->hibernate and then turn off the hibernation feature AnswerOpen your registry: and find the key PowerdownAfterShutdown and set it to "1" to power off the computer at shutdown, or "0" to reboot. Here is the path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Winlogon If you don find it, create it(REG_SZ (String Value)) restart windows AnswerAll are very good answers. How are you shutting down your computer? Do you go to start shut down and then press ok or do you hit alt + f4? First I would check to see if my PC was set on restart in the shutdown window just before you click ok. If it is change it to say shutdown. Then I would try some of the other answers but they take a good knowledge about computers if you mess up. Hope it helps. AnswerFirst go to your start menu and then right click my computer and click properties.

click on advanced tab and then under startup and recovery click on settings..

then under system failure uncheck the automatically restart....

AnswerLook in your bios for a Wake on Lan option also.

Why would your computer freeze up after defragmenting the hard drive?

Moved FilesOne reason may be because files were moved and your computer needs to be restarted cause the computer was reading the files and they all of a sudden moved. Physical FaultsOne possible reason for this is that your hard disk is developing physical faults. Sometimes these faults may not be picked up by tools like ChkDsk however chkdsk is a good place to start I would advise using the /r option. There are other free tools around that can help you identify Hard disk Faults like "Drive Fitness Test". If any of these tests show that the hard disk does have faults it should be replaced as soon as possible. Software is available that will enable you to clone the faulty drive onto a new one.

put your computer in SAFE MODE.THEN DEFRAG.

Check your hardware in device manager and see if there are any conflicts,(yellow ? marks), beside your display adapter, your monitor, and your sound drivers), sometimes a driver can become corrupt and you may need to update it. Also The defrag could have defraged a file in your registry that is no longer used, I recommend buying Registry Mechanic, this will fix any errors in your registry that can also cause freezing. One last thing, go into safe mode, and do a scan on your hard drive for errors, make sure before you do the scan make sure the box is checked for,"automaticaly fix errors". Then when that's all done, do a defrag in safe mode.

Like you I have had problems defragging, but I think that in my case it was something wrong with the defragger, as when i did it 2 weeks ago, then my computer crashed doing this, i restarted, 'Cannot Find Hard Drive', so then it went to a comp shop they fixed it, did disk defrag again, then computer restarted with the same problem, then it started to go through, 'Used Clusters' 'Unused Clusters' 'Bad Clusters' then here it takes forever to do then the computer frooze, so i turned it off, went and bought a new computer


Your problem is either a driver, harware or heat issue. Try updating chipset drivers with the original that came with your motherboard if it doesint work update with windows update to get the a signed driver, check to see if your hdd is running hot if you cant touch it get rid of it, update your bios if this occurs when you have just changed your hdd, disable the s.m.a.r.t function in bios if your hdd is older than 9 years old and lastly has i have seen enough before your video card is failing, change it.

Please perform the steps given below to increase you system performance.

1. Uninstall all the unwanted software.

a) Select the quickest hard disk.

b) If you have, two hard disks that are similar in performance select the hard disk that does not contain Windows system files.

c) Make sure the drive has free space equal to at least twice the size of the recommended swap file size.

d) If the partition is on the same physical drive, select the partition in alphabetical order. For example, if you have one 2GB hard disk and you partition it into two 1GB partitions drive C & D) You should pick Drive C over Drive D if meets all the guidelines of a, b & c.

9. Set the Minimum/Maximum to: With large hard disks settings a 128mb or 256mb swap file should be sufficient in almost every situation.

Note: The amount of RAM plus the size of the virtual memory file is the maximum amount of RAM you can use at once. Win386.swp is the filename used for the swap file. The file is quite large don�t delete it.

10. Click OK.

11. After setting the size of the virtual memory file windows will display the following message. You have chosen not to let windows manage virtual memory automatically. Click Yes.

11. You must restart your computer before the new settings will take effect. Do you want to restart your computer now? Click Yes

12. Sometimes Windows 95 takes a long time to shut down. During this time, it is doing necessary system maintenance. You must wait while the computer shuts down.

Also try using a registry cleaner, some file paths may be redundant, a registry cleaner will fix these errors. Visit for top rated cleaners

13. Actually this problem bothered me quite a long time too, but recently I find functional software which can fix all these problems just with one click: tuneup360, maybe you guys could have a try.

Why is my computer making strange whirring noises?

The whirring noises you hear are coming from the fan trying so hard to cool down the PC. This occurs when your PC is heating up as a result of overuse, or multiple programs running at the same time (mostly on the background) when the RAM size or Processor speed is low. Your PC tries to compensate for these lacks and try to keep the PC in optimal condition. When the PC starts making such noises, it's an indication for you to take it for some maintenance. The fan also needs to be clean. It can also happen is you are using the PC in a particular place of increase environmental temperature. I remember how once I had to keep my laptop in the refrigerator to cool down (lol). Another reason why the PC might be making such noises is if it fell at some point.

Why would a PC lock up?

Usually a PC locks up due to hardware or software conflicts. You can tell if it's a hardware conflict if the lock ups occur while using the same combination of equipment (e.g. printing while downloading something off the web). This was more common in older systems - but I haven't experienced this problem with newer PCs in the past few years due to their achievements in making equipment compatible with other vendors.

More commonly, a lockup is due to software conflicts. These are harder to troubleshoot, since they could appear randomly. Most times, this is due to a lack of memory. If you have a lot of software on your PC, they could be using most of your free memory. If you're running 128Mb or 256Mb with a Windows 2000 or greater OS, then you're probably lacking in RAM.

In the Task Manager, check out the Performance tab & peep the memory section (the 2nd graph Page File Usage History). If the yellow line is anywhere near 1/2 way through the grid, you might want to upgrade your memory or uninstall memory-hungry apps.

With today's prices, upgrading RAM is quite affordable. As for uninstalling unnecessary application, go to Control Panel & then to "Add/Remove Programs". Search for any unrecognized and unnecessary apps & remove them.

A computer may lock up when the hard drive is fragmented or almost full, and the registry is full of junk from previously installed programs. See related questions for advice on cleaning up.

If your PC doesn't give you any messages and screen is frozen, it might be hardware conflict or heat, but if your mouse still moves then I would check my video card, update drivers and check the temperatures.

Also, viruses and adware contribute to instability. So if you have tried nearly everything else, run some spyware and virus scanners. Back when Windows 98 was popular, some people complained of a green dot in the upper left corner of the screen and instability. That was spyware that did that. Removing the spyware made the dot disappear and the system lock up less.

If all else fails, it is probably the motherboard. Motherboards contain electrolytic capacitors which serve to filter the current (among other roles). With time, they may swell, leak, or explode. There are places which will replace them for you. Also, motherboards can develop broken traces and loose connections. In some cases, the problem is the ROM BIOS, and you can often flash it with a newer version that makes it more stable.

How do you use an anti static mat?

An anti-static mat is usually made of a conductive plastic. Usually, on one corner there is a snap connector. From that snap connector there is a long, (usually GREEN) wire, as well as a coiled wire that goes to a wrist strap. The green wire goes to the round GROUND connector of an AC wall socket. The coiled wire that goes to a wrist strap goes just like that. Wrap the wrist strap around your wrist.

The reason for this setup is, through the green wire to the ground connector, you put both the mat and your body at ground potential. It takes the static electricity from your body,via the wrist strap, and from the mat to ground.

Be VERY CAREFULL!! YOU MUST KNOW WHERE THE GROUND IS ON AN AC OUTLET TO USE THIS AS I HAVE OUTLINED. If you do not know where the ground pin is on an AC outlet, you should not use it.

Why would your computer reboot itself every 5 to 10 minutes?

While some of the entries below may work, most are simply too complicated for the average user and many are overkill. If it is spontaneously rebooting at relatively regular intervals it is MORE than likely a cooling problem. If no hardware has been changed inside the case since before it started doing it then that is most likely not the problem. Assuming all of the above, probably all you really need to do is check for a faulty fan (if the fan is the problem USUALLY it will be making noise different from what it was before the problem started.) If faulty, simply replace it. If the fan appears to be good then check for dust build up in the heat sink (sits on top of the processor and generally has a fan on top of it or a plastic conduit of sorts so it can utilize the case fan) or vents in the case housing itself. If, and only if, that doesn't fix your problem THEN you can consider doing some of the other stuff listed below. IF YOU DON'T UNDERSTAND EXACTLY WHAT THEY ARE TALKING ABOUT, DON'T DO ANYTHING EXCEPT TAKE IT TO A COMPUTER TECH AND LET THEM TROUBLESHOOT IT FOR YOU. Simply replacing parts, unless you happen to have identical spares laying around, can drive the cost of repair very quickly to the point where you would have been much better off to have simply taken it to a professional to begin with.


If your computer is about 5 years old, it could be capacitors on the motherboard.


The problem could be a software conflict. You should probably uninstall any newly installed software and clean out the registry of any corrupt entries and remove all .tmp files from the hard drive. Also, check that your services start normally and there are no conflicts there either.


It could be your CPU getting hot. Check the heat sink to see if it is hot. It could also be your RAM (get memtest and run it for a few hours) and it could be your power supply.


You might have the w32.sasser worm (a backdoor Trojan). Norton AV has info and fixes for this for free.


You could have the shut down temperature too low. You change this in the BIOS.


The other side of the above answer, instead of your computers shut down temperature being too low, maybe your computer is just generating a lot of heat. You can check your running CPU temp at the BIOS screen.

If it's running to hot you can either add more cooling, or knock down how much heat is being produced.

To lower the temp you might do the exact opposite of overclocking (underclocking?), slow down your CPU and BUS speeds.

If you want better cooling add more fans, or if you really want it cool, install a water cooling system. It's more expensive (at least a hundred dollars) but it's worth it. Try the Aquaries Aquatake gear if your CPU temp is the problem.

Other products to consider: A digital temperature gauge that loads into an empty bay, so that you can just look at your computer and judge the heat.

More fans, maybe with some cool LED action.

A multi-speed fan controller, which will act like the gears on your ten speed bike. Multiple gears means multiple different fan speeds, and many will allow you to control many fans.


Check APM settings in Control Panel


The power settings probably have it do that. To keep it from doing that go to start > settings > control panel> power options> and make sure everything is on never. That might fix it.


Make sure that your computer gets plenty of ventilation. Don't put it inside of a cabinet, or some other place where it doesn't get adequate air circulation. Move things like books and boxes from around it. Clean out the dust. Are the heat sinks plugged with dust?

Overheating can cause the capacitors on the motherboard to leak or explode, rendering your motherboard useless. If in doubt, ventilate.


In addition to the above problems, you could also have bad RAM. To find out of your RAM is bad, swap it out with a set of good RAM (from another machine that is working, or if you don't have another computer perhaps you could borrow some from a friend). If the problem ceases, replace your RAM. If you swap it out and still have the same problem, then your problem lies elsewhere.


Everything On the Page is a Possibility

If you are using Windows XP it could be faulty software or some sort of missing file in the Windows XP OS. Windows XP comes with a nifty little feature that detects software errors that can potentially fry some piece of hardware in your computer. If you are getting thrown face first into a blue screen with white text, it should tell you that it terminated Windows for the sake of your investment in the computer hardware (that's in a nutshell pretty much). If you do get the blue screen just reinstall Windows, but im guessing its just totally shutting down when you say "reboot". Its not common for Windows to hit a software malfunction and instantly reboot (should go to the the blue screen of death) but it still happens more frequently than it should. But for the most part it is probably not bad RAM seeing that if the RAM was bad it would not get past the motherboard diagnostic screens (the ones that tell you the Masters, slaves, and total RAM in KB) seeing the computer has no Random Access Memory to temporarily store and swap files for the tasks needed to run when you boot Windows. Obviously the RAM does work enough and everything is probably just fine as it is functioning enough to get to Windows and is a sign that it is overheating.

As stated above, overheating is probably the major concern here. Try leaving the side of the case off and letting it vent. Get some canned air computer duster and clean out the Fan and heatsink on the processor just incase that's what is overheating it. It is usually the CPU or Graphics Card that is overheating. If you think RAM is overheating, tape a stack of 2 or 3 pennies to each chip on the stick, copper makes for a good heat conductor. If the power supply is getting old it could be creating spikes in the computer's power. Don't count out the fact that it could be a problem with your home's power. Your power could cause a brownout. If you think that might be the start of all of this, get a UPS[Uninterrupted Power Supply] to fix the flux problem then a new PSU plus what ever you think is faulty(of course).

Do not plug in any good pieces of hardware into your computer until you know for certain that its just that piece, whatever it may be, that is toasted out only. Otherwise a messed up motherboard could just fry whatever you just bought or tried to use in about a nanosecond.

If none of the Answers here work for you and don't help by reading this, start from the top and work your way down. Determine your house's power stability (please, always use a Power Strip with the 3rd prong unless you want to watch your PC go *ZUMP* in the middle of a thunderstorm).

Simple guidelines to follow when figuring out the stability. Does my screen seem to flicker/shake when something turns on? Does the light on the power strip flick on an off or dim in and out? If possible buy a UPS and a large wattage capacity PSU from a trusted manufacturer (those generic ones are a great way to end a PC too).

Move onto the RAM and determine their status, usually by swapping as stated in an above Answer. If you have 2 sticks of RAM and more ports than you have ram, try taking one out, then swapping it and using the same port with the stick you took out first then just repeat the process down the line of RAM slots one at a time. If there is still no go, find someone gullible enough to test a potentially hazardous piece of hardware in their computer.

Next move onto the CPU, check the CPU Fan RPMs then figure out what the standard RPMs for that Fan is (you can figure this one out by probably looking around on the box to the fan or the fan itself most of the time). If you figure the CPU is overheating, which happens 75% of the time, get a water coolant system if possible or buy a High RPM fan with a tall copper (not copper plated) heatsink and find a good brand of Thermal Paste. Extensions you can buy for the standard heatsinks and fan setups are almost useless. Buy a Fan tube instead so it will direct the heat out of the case instead of just dispersing it inside the case.

Testing a CPU can get annoying considering finding someone willing and has the same socket as you do is extremely tough to find. If you cant find anywhere to test it, just leave it there and move along to the next step.

Check the Graphics card any way possible, not exactly hard to find a someone with a AGP or PCIe anymore. Next comes the hard and disc drives. If they boot up when you turn it on you should be good to go. If you are not satisfied with listening for some whirling and humming, it is even easier to find someone willing to test a HD or a CD/DVD. If you can't find someone to do that, just unplug the CD/DVD drives and go into your motherboard BIOS (assuming it at least gets to that point) and change boot device to a HDD.


The issue could be the age of the computer or that there is a system failure

  • Check the motherboard capacitors. If they seem bulged from top and bottom with fluid popped out (if gone worse), the caps should be replaced.

Note that replace-capacitors should balance voltage. (New caps should be of the same voltage.)

There won't be the exact original cap available in store. But you could replace with same capacitance and a different voltage (larger).

Why would your computer start up again after you shut it down?

Several things may cause such a problem to occur.

If you're using Windows XP, see the following Microsoft Knowledge Base article for more information on possible causes and solutions for such a problem:

Additionally, check out the below web page link for more good information regarding Windows Shutdown & Restarting problems:


A power surge can cause that.

Or a defective power supply.

Is there a simple way to import files and programs from an old computer to a new one?

One option is to remove the hard drive from the old machine and change the jumper setting (these are small pins on the back of the drive with a small clip that makes a connection between 2 pins- there are usually 3 basic settings marked "M- for master, "S"- for slave & "CS"- for cable select) to either slave or cable select then install the drive on the second connector (closer to the middle of the cable) on the IDE cable (the flat multi-wire cable with rectangular connectors) and transfer the files through windows explorer. Or, instead of messing with jumpers, just unplug your CD/DVD drive and plug the other hard drive there temporarily. For SATA drives, just plug the drive from the old machine into an open SATA socket.

If the new machine is a Win XP or Vista based machine then you can also use the "Files and Settings Transfer Wizard" function.

You can burn your files to DVDs.

Another option is to get a USB flash drive. It is a small device and comes in various amounts of memory space. A 128 MB or a 256 MB can store more data than you can imagine and should help you in transferring your data. An external hard drive is another option. Then just copy and paste.

You can do it by configuring FTP on one and client FTP on other. Otherwise it can be possible through network device.

Transferring programs from one computer to another is a difficult process. However, there are 2 programs that I know that do it. See the links in the section below to get them. Laplink's PC mover is one commercially available application that should do the job well though. If you don't want to fork out the cash for PC mover there is a beta of a program out there called "Pick-me-App." It can't transfer all applications yet, but it works pretty well for a lot of applications.

What causes a personal computer's monitor screen to flicker sometimes?

Your monitor is probably alright. If it was going bad, you would most likely start to see a constant black stripe on the top or sides. Some monitors naturally flicker some when playing videos, such as certain Acer flat-screen monitors.

It could be a sign that you are using the wrong refresh rate or the wrong video card driver settings. Try updating or reinstalling the video card driver (the software that runs the video card).

You could be running low in RAM or just hard drive space, so try removing unwanted programs, games, pics, videos and even documents. Then defragment the hard drive. This would more likely just address a jerky display, not actual flickering. Check that your PC's fan is not clogged with dust, to make sure the system is not overheating.

Sometimes malware (viruses and spyware) can cause video issues. For instance, one type of spyware displays a green dot in the upper left corner of the screen.

Computer Maintenance

Why would your computer shut down only 20 minutes after you start it?

A common cause for shutdowns is the CPU overheating. Check the fan to make sure it isn't spinning slow or seized, and that there is no dust in the heat sink. You can also check that the heat sink compound (the paste between the fan and heatsink) hasn't broken down.

Or your power supply could be going bad. It gets hot and then shuts down. It might also be a bad power supply fan, that is the power supply might not be getting hot because of a problem with the power supply but because the fan isn't cooling it properly.

Also, check for bad capacitors on your motherboard. Capacitors are small, cylinder-like things with an aluminum top, with some type of molding or lines on the aluminum. There are many ways to find out if you have bad capacitors:

1. A brown, crusty substance on the capacitor or motherboard

2. The capacitor is swelling

3. The capacitor "venting"

4. Signs of overheating

5. A pop, with a hiss after it coming from your computer, or even a small explosion

6. Capacitor blows off its casing

If any of these symptoms appear, repair the motherboard ASAP. Power supplies also have some capacitors, but it is strongly recommended to avoid these unless you discharge them first because they can still have a charge in them, which could be deadly.

How do you speed up your computer?

You can speed up your computer in a number of ways. For instance you can clean your Windows registry through an efficient Registry Cleaner and PC Optimizer such as Reginout. Similarly you can uninstall unwanted softwares and disable unused programs. Keeping a shorter list of startup programs helps to speed up your computer start up.

A computer can be made faster by:

1. Defragging it regularly using Windows Disk Defragmenter.

2. Deleting the temporary files in the system.

3. Reducing the number of programs that start during windows startup.

4. Optimizing system configuration

5. Adding more RAM [memory]

6. Upgrading the CPU

7. Upgrading other components such as Graphic Card

Steps 2, 3 and 4 are usually done using software. 'Advanced WindowsCare Personal' is a good option. It is free for private use and can be downloade.

Without spending money:

Eliminate all the extraneous software from your machine. Seems like everything you download these days wants to run an "agent" on startup, & all it does is sit there & soak up RAM & CPU cycles. If your system tray (down by the clock) is crowded, get rid of as much of that stuff as you can. Additionally there are many gray-area malware apps (spyware adware scareware) which may or may not be picked up by your virus scanner.

Below, i will link a couple good programs for removing this stuff. First is "malware bytes," it will help you find any malicious or semi-malicious programs running on your machine & remove them for you. Second is "decrapifier" it is intended to be used on a newly purchased computer and will help remove all the pre-packaged demo-ware which comes with new computers.

Be sure you have at least 10% free space on your hard disk & then defrag your hard disk. The defrag utility is in start> accessories> system tools.

If you don't mind spending a little money:

Adding system RAM can greatly improve the performance of any computer system. It's like putting a turbo-charger on your car, the engine is the same, but it produces a lot more power. You can never have enough RAM for windows, & adding RAM is always a surefire way to get a little more performance out of your machine.

Upgrading your video card is also a good way to boost performance in 3d games. Modern video cards have come a looooong way in the last couple years and a decent 512mb card can be had for under $100.


If you're discussing a machine which once ran better, but is running slow now, your best bet is to do a few system-maintenance measures to speed things up a bit.

First, do a good spyware scan. Spybot search & destroy or lavasoft adaware are both excellent freeware programs which will scan your system for useless software & remove it automatically. Both are linked below.

Second, see all that crap down in your system tray (on the start bar by the clock), all that stuff is queued up to run on startup & then just sit there soaking up RAM and CPU cycles. Go through those programs & go through their prefs & tell them to stop loading on startup. Failing that, spybot also has an excellent utility for removing unwanted programs from the startup routine.

Third, optimize your operating system. Windows by default loads up all sorts of services that may or may not be necessary for your particular usage needs. I suggest googling for "windows XX optimization guide" with XX as your windows version for more info on what you do & don't need.

Fourth, and maybe this should be first. Unplug your machine, take off the side, & blow out all those dust-bunnies. A clean computer is a cool computer, and a cool computer might run faster.

To make the PC faster, make sure you don't have infections, keep the HDD well organized. IMO the HDD can be the slowing down factor on an otherwise well equipped system. Be careful about downloading and installing the programs and defragment regularly to keep data access smooth. In fact you can even automate the task or get a defrag program that will proactively tackle fragmentation. Besides this run a disk cleanup often and ensure your security updates are in place.

To get the most performance from your PC requires allits components to be operating at their full capacity at all times.

By far, the slowest component in any system is the hard drive, since it is mechanical and is in constant use (even if when only web browsing many pages download temp files to your system to access their content, causing items to be written and read).

And easily the biggest destroyer of hard drive performance is fragmentation, as having pieces of files and free space randomly scattered all over your disk necessitates a lot more disk action to write and later access the files than would otherwise be needed (even insufficient RAM boils down to slowed disk performance as the page file will have to be used more when RAM is low).

So while getting more RAM will certainly help (mainly because the disk will be used less -- till the RAM is used up), the real bottleneck occurs at the hard drive -- it's the weakest link in any system.

That being said, the best investment would go in the direction of getting and using advanced third party defrag solutions that can automatically defrag your disks as needed, not overnight or "once a month", but now, when the disk is being used.

Please see the links below under "Top 10 Review of Defrag Solutions" and "Defrag".

You may have never noticed that how many unwanted programs you have installed on your computer. The programs consume system resources while they are running. The more programs you have running, the more system resources the components consume. These components can dramatically reduce the system performance and slow down PC speed seriously. To improve computer performance, you may consider enabling Windows Add/Remove app to uninstall the large bundle of the programs you have seldom used.

To uninstall common programs from your computer, you may consider applying two methods:

  • From All Program List: Start > ALL Programs/Program Files >Scroll to the Program > find out the uninstall utility of the program and then click it

Keep PC Away from Spyware

Spyware refers to any technology that aids in stealing your private or business information from your computer for commercial purposes through sneaking into your computer and seriously degrading your PC. Especially when it requires huge amount of system resources and network bandwidth to spread itself to remote PCs, it can drastically slowdown system performance or cause the computer to be sluggish. If your computer is experiencing the problems below, you may consider checking whether your computer has been deeply infected by spyware:

  • Unexpected Blue Screen of Death errors
  • Mysterious system pops- up
  • Drastic deduction of system performance
  • Slow computer performance
  • Network connection failure
  • Lost of personal information
  • Lost of online bank account login credentials
  • Browser freezes
  • Numerous links to ads sites located on the desktop

To improve computer performance and wipe out spyware from your computer, you may consider running Microsoft Security Essentials on your computer. Microsoft Security Essentials is a new, free consumer anti-malware solution for your computer. It helps protect against viruses, spyware, and other malicious software.
Without adding faster hardware there are some things you can do to make it faster.

Remove Viruses

Clean Temp Files

Fix Registry

Disk Defrag

Edit Startup

Change Performance Settings.


1. Remove spyware and malware

Spyware is notorious for it is especially designed to obtain commercial gains through exploiting your private or sensitive information, without your consent firstly. In case that your computer has acquired spyware and malware, there may be a list of system problems are going to annoy you constantly:

  • Unexpectedly Blue Screen of Death errors
  • Tons of .dll errors, .exe errors
  • Distinctive reduction of system performance
  • Frequent computer crashes
  • Driver update blocked along with Black Screen of Death error
  • Browser hijacked
  • Ads toolbar bombard
  • Undesirable modification on system setting
  • Firewall inability

To combat spyware and fix slow computer, you may consider enabling the built- in Microsoft Windows Malicious Software Removal Tool to free scanning your system and easily wipe out the large number of malware from your computer. Microsoft Windows Malicious Software Removal Tool empowers you to easily handle with any level of dangerous infections with its industry- leading spyware removal utilities. Furthermore, to avoid any unexpected modification on the third-party anti-spyware programs, you may need to enable a registry optimizer to protect and control over the programs' registry keys.

2. Clean up the disks regularly

The massive number of unwanted or obsolete files in C:\ may be a big reason that drastically decrease the system performance and generate a list of further obscure system problems. To fix slow computer and tune up the overall system performance, you may consider enable a disk cleaner for cleaning the files, including temporary Internet files, previously installed program files, files in Recycle Bin, Windows error reports, unwanted system components, obsolete files generated by system restore and unneeded third-party programs.

3. Disable the unneeded programs at system startup

Some software manufacturers attempt to recover their development costs by setting the built- in components of their programs to run at system startup. This can drastically decrease the system performance and waste a lot of the PC users' time for waiting the system to boot, especially when the users do not have much computer experience. To efficiently speed up computer and optimize the system to its peak performance, you may need to disable some system components that you do use it anymore at system startup time. Remove all the big files from your desktop. If your hard disk is full get some external usb hard disk and move all your movies and pictures there.

4. Keep the registry error- free

Windows Registry is considered to be the kernel part of the system for it is mainly used for storing crucial system settings for the Windows operating system. Any registry errors or problems have the ability to bring about further complicated computer to your computer, especially a slow computer.

5. Defragmentation is a good idea.

Hard Disk Drives

Why would your computer be only 2 percent defragmented after 24 hours?


Anything that interrupts the computer's defragmenting process will cause it to start over again. This means any program that is running in the background that accesses the disk while defrag is running will do it. The best way to deal with this is to start your computer in Safe Mode, stop all your services and background applications, and then run the defrag again.


It is a lot easier to just stop programs like screen saver, and automatic retrieval of emails before starting to defrag the hard drive. These are usually the applications that make the disk defragment start over time and again.


At that point I would try what the contributor said above, but if it didn't work, at that point I would just back up all your files that you want and then format your hard drive, reinstalling Windows. Reinstalling an OS is the simplest way to get rid of persistent problems: all you need is the legitimate copy and your backed-up files! btw: you'll have a clean slate!

Keep those restore discs! If your PC didn't come with them, then you should be able to make them. It varies with every manufacturer, but you will need several CDs or 2-3 DVDs in general.

How did the hard disk get its name?

The first discs that were made for computers were made from a thin material that bent easily. These were referred to as floppy disc then a smaller disc with a hard plastic cover was brought out to replace this which was originally meant to be referred to as a hard disc, however at around the same time the discs that computers ran on were also looking for a name and these ended up being called the hard disc and the new rigidly encased discs went back to being referred to as floppy discs.
