Computer Maintenance

If you mean by a "general advantage", then they provide lots of advantages. Such as banking, (social) networking, research, paying bills, organizing files, preserving old documents, gaming, etc...

Sounds like it could be an electrical problem...possibly bad battery, alternator, or starter. If there is a sound sort of like a machine gun when you crank it, but the engine won't turn over, then it's the battery, and possibly the alternator; if there's just a clicking or whirring sound, that's the starter; if nothing happens at all, that's the alternator, and that also means the battery is probably dead. Has your red battery light come on on your dashboard? Also could be failed ignition control module, ignition coils, or badly worn spark plugs. I would check the battery, alternator, and starter first. If you can get the car jumped, take to an auto parts store, and they should be able to test your battery and electrical systems' integrity for free. Plus, I think you mean "quarts" not "liters" of oil. If the problem's oil related, I'd have the car checked for leaks with a compression test by a mechanic. Or it could be the computer going bad. Once again, a mechanic would be the best person to see. If it does turn out to be the computer, this is one of the very, very few times I would take it in to the dealer to have it fixed. Hope this helps. Best of luck!

Mixing memory of different types and latencies is not particularly a good idea. But you can often make them work together if you must and if you know what you are doing. If they are in the same bank, then you would likely have to override the detected memory settings in your CMOS. In that case, you'd usually have to use all the worst timings of the two (larger numbers). In this case, you'd have to use a latency of 5. This might be listed as CL or CAS if your motherboard will let you manually set the timings.

However, there is an exception. If you are also mixing speeds, you would have to use the slower speed. But if the faster memory has a higher latency, you might still get by with the lowest latency of the two. If you overclock memory, the latency gets worse, so if you underclock it, it gets better. The latency number is calculated by the rated speed, but it is measured by clock cycles, not by time. It would make more sense to end users to measure the latency by some time unit, but the memory controller has to know how many clock cycles to wait. You would likely need to convert the latency to nanoseconds. One formula is:

(CL/(Freq-in-MHZ) * 1000) = speed in ns

For DDR, remember to half the chip's label frequency. This formula will allow you to compare latencies, and if you reverse the process, you should be able to generate new compatible latencies if you must use the memory at a different frequency from the rated. If you must round latencies, go higher.

There is a mathematical formula run across the binary form of a file. The answer to that formula is a files "checksum." This can be used later to ensure a file has not been tampered with either on purpose or by accidental corruption such as the results of a bad file transfer.

When Spybot gives you the "Bad Checksum" message it means that the file it received does not calculate to the same checksum as was recorded for the source file. The most common "fix" for this is to perform another transfer of the file. Spybot's update process being run a second time should resolve the problem.

Press ctrl, alt and any of the arrow keys at the same time to rotate the screen. If an arrow doesn't work, try a different one.

Go to the printer manufacturers website. What you need is the "driver" so that your system will recognize the new printer. Recently did this for a couple year old flatbed scanner - works great.

From the command line (in windows) you can access many of windows internal features such as trouble shooting the dll structure and network analysis for more information you can type 'help' in CMD (command line)

Most other operating systems have command lines, such as Linux and Ubuntu

WARRNING: you can really damage your computer if you don't know what your doing

The best thing to do is check the website for a mention o Open Source. see www.ubuntu.com and open source applications that you know of to see what you are looking for on the site to see if it is open source.

Binary Code

The usual method to install a linux type operating system (Ubuntu, for one example) is to first download the program, burn it as an ISO onto a CD, and make the CD drive as the first boot (rather than the hard-drive) by entering the BIOS. Then, with the CD in the drive switch on the computer. You will eventually be offered the choice of running the ubuntu operating system as a live-cd, which doesn't alter any settings or your present OS, as it is run entirely in memory (RAM), or install Linux Ubuntu (either as a dual-boot or do you want it to use the whole of the hard-drive). As to why there is a disc already there? Maybe the BIOS has not been set to make the CD drive the first boot?

First open the terminal and type "sudo mkdir /media/MMCSD" Then type "sudo nano /etc/fstab" Then scroll down the entry starting with /dev/sdb1 delete the line and in its place paste this line /dev/hdb1 /media/MMCSD vfat auto,user,sync,exec,uid=1000,gid=1000,umask=007 0 0 This will give you full root access to your sd cards I recomend the this one^ Or you you can type /dev/sdb1 /media/MMCSD auto user,auto,exec,rw o o This won't give root access to the card (i.e can save or make directorys on card)

The area on the hard drive that contains a map to all the partition on the drive is called the partition table. That is what partition utilities edit when you add, delete, convert, or resize a partition.

Restore your computer to an earlier date when you had saved your file or

Using ERD Commander disk to recover deleted files.

Generally the second option works more better because i have used that.

Most batteries are expected to last 3 to 5 years.

It's called D-Sub or VGA cable.

The monitor hold 20,000 or more volts (depending on the monitor size and components). Voltage can still be present after turning off the power. Most technicians who work on monitors have special training in working on high-voltage equipment. If you must remove the monitor case to work inside a monitor, safety rules include the following: (1) do not wear the antistatic wrist strap; (2) unplug the AC cord from the monitor or wall outlet; (3) do not use regular test equipment to measure the monitor's high voltages.

There are several different lights on a typical motherboard, each meaning different things. Different colors also usually indicate different types of status (e.g. green informational, red problems). If you can get the manual for that motherboard there will be a list identifying the meaning of each LED.

Most likely an LED that you have never seen light up when the machine worked but now lights up is indicating a low level hardware failure that prevents operation.

I have a desktop computer that has 7 or 8 LEDs on its motherboard, although all of them are red LEDs the manual identifies all but one as informational status lights, the remaining one which is slightly offset from the line of the others is identified as "fatal hardware error" and if it lights at any time the computer cannot operate in any way.

Hertz is the measurement of cycles per second. The range that microprocessors use for personal computers are currently:

Megahertz

Gigahertz

PC organization is keeps your computer organized. This includes, but is not limited to:
1. trashing old files
2. cleaning the drive
a: removing unused folders
b: freeing space
3. tidying up the hard drive and desktop by removing unused items
4. remove programs that are unused

Depends on what they used if you remove the CPU heatsink you mite have to remove the CPU with it. If the heatcontact was a glue type then u cant without removeing the proccesor
