Computers

You can try, I did, but 2 days later I got a call from the police...

Your anti-virus will say it's dangerous but ignore that, it is correct it is a virus, but not one that is dangerous towards the computer, it hacks Sony and generates fake license codes. It's very risky. I'm never doing it again, music is cool though

When a computer saves a file to disk, it looks for the first piece of unused space (not necessarily a space big enough to save the file !). On finding empty space, it attempts to save the whole file. If the space is too small, it saves as much of the file that will fit, then searches for some more space until it's saved the entire file.

This creates fragments of the file on the disk, which are linked by a 'tag' so the computer knows where each part of the file is. Having to search for fragments of a file can make a computer seem slow, as it has to wait for the hardware to find the pieces of the file before it can do anything with it.

A disk de-fragmenting program collects all the 'pieces' of each file, copies them to memory, erases them from the disk, then re-writes the whole file to disk in one single piece. Regular de-fragmenting speeds up the computer, by reducing the time it takes to find each file.

yeah, soo much better get a laptop..a HP laptop is pretty good

It is never "safe" to kill a process, svchost or otherwise. Processes should be stopped using their defined interface. Failure to do so can result in data or system problems, due to possible error and inconsistency. Processes do "run away" or fail to respond. Killing them is often the only way to stop them. The computer should be rebooted if a svchost, or other service, process is killed. Data corruption might result, and restore from backup might be needed. (You do keep backups, don't you???) If you need to kill a process more than once, you should consider that something is wrong, and needs to be fixed.

From what I can gather, it appears to be a video compression software. I ran a file scan and it seems harmless. It's safe to remove from your PC. The file usually has an included installer.

Computers need a method to store decimals. More to the point, they need a method to manage very large and very small numbers - numbers that we would normally show in scientific notation.

no not at all infact it makes it faster if u get the toolbat

Pull out CPU and turn on your computer, if you hear BIOS error complaining about CPU absence: most likely your CPU is dead. Also try to test power supply harness. All required wiring diagrams and standards you can find in internet, just use google.

Through layer upon layer upon layer upon layer ... so on and so on ... of abstraction.

I'll do my best to give some layers.

At one of the lowest levels is electrical components such as resistors capacitors etc.

Put a couple of them together and you create a circuit, throw in some logic gates (AND, OR, XOR etc) and you have some logic handling.

If you arrange this logic gates into some basic configurations you can make circuits capable of math, memory addressing and other advanced tasks.

Put all these peices together with some more advanced connections (Buses etc) and you get a CPU. (You can repeat for other peices for hardware too)

. This CPU is capable of executing some basic instructions called Machine Language, this is basically some numbers that stand for certain memory positions and calculations and logic jumps.

Then to make things easier for people the Assembly language was invented, this assigned some simple words to those machine code numbers and added some automated help (registers etc).

Next comes some basic system calls. Assembly code written that controls your hardware.

Those system calls combined with some other nicities such as memory management, and you get the operating system (OS). (Windows is essentially just this with some pretty windows ... hence the name)

Although assembly is already a step up its still not enough. Eventually other programming languages were invented to make programming easier. Those languages take the code and translate it into machine code.

Using these programming languages programmers can create the programs you use.

Obviously this isn't 100% complete, I missed libraries and device drivers and all that lovely stuff, but the above should give you the general idea of how computers are really just layers and layers of things built one on top of the other to what you use to get your answers.

What happens When a PC Powers-up?

When you turn it on, a computer's power supply must bring all the separate voltages required by the Motherboard and peripheral components to an acceptable level with enough current to power the whole system. These voltages include both + and - (plus and minus) 12.0 V (volts), + and - 5.00 V and most likely +3.30 V (which may be reduced even further by circuits on the motherboard for the latest power efficient processors). [ Note: All these voltages will vary slightly for each combination of power supply, motherboard, disk drives and various peripherals (since all electronic components drawing current will alter the power supply's load), but they should never fluctuate by much (if at all) upon reaching their operating levels. If a power supply isn't quiet enough (i.e, it has too much AC noise on any of its outputs), the motherboard's BIOS chip may not function correctly; or more likely, the Memory portion of the Power-On Self Test will fail. Either way, the system will never boot up completely! In locations where the AC input from the power company experiences occasional problems or total loss thereof, devices which store up power for a some minutes, allowing you to save your data and properly shut-down the system, should be used. ]

Due to the sensitive nature of some IC chips (Integrated Circuits inside small metal, ceramic or plastic packages), especially the CPU (Central Processing Unit; which produces a great deal of heat, thus the reason for a large metal heatsink and fan on it), the motherboard may never be allowed to power up until a power good signal is received from the power supply. This may take over half a second; a tremendously long time when compared to the speed of a CPU that can step through millions of instructions per second (MIPS), yet it often seems almost instantaneous to its human operator.

By the time you notice the sound of a fan rotating or drive motor spinning up, the voltages have already stabilized, power has been applied to all the chips (the interface chips that facilitate communications between the CPU and the Memory modules; along with any audio, video or LAN cards plugged into bus connectors, and the controllers for peripheral devices such as keyboard, mouse, hard disk and CD/DVD drives) and the motherboard's Clock-pulses are already synchronizing all those interactions. In what feels like a fleeting moment to us, the PC is already executing instructions from the BIOS (Basic Input/Output System) chip.

When the processor first starts up, it is suffering from amnesia; there is nothing at all in the memory to execute. Of course processor makers know this will happen, so they pre-program the processor to always look at the same place in the system BIOS ROM for the start of the BIOS boot program. This is normally location FFFF0h, right at the end of the system memory. They put it there so that the size of the ROM can be changed without creating compatibility problems. Since there are only 16 bytes left from there to the end of conventional memory, this location just contains a "jump" instruction telling the processor where to go to find the real BIOS startup program.

3. The BIOS performs the power-on self test (POST). If there are any fatal errors, the boot process stops. POST beep codes can be found in this area of the Troubleshooting Expert.

4. The BIOS looks for the video card. In particular, it looks for the video card's built in BIOS program and runs it. This BIOS is normally found at location C000h in memory. The system BIOS executes the video card BIOS, which initializes the video card. Most modern cards will display information on the screen about the video card. (This is why on a modern PC you usually see something on the screen about the video card before you see the messages from the system BIOS itself).

5. The BIOS then looks for other devices' ROMs to see if any of them have BIOSes. Normally, the IDE/ATA hard disk BIOS will be found at C8000h and executed. If any other device BIOSes are found, they are executed as well.

6. The BIOS displays its startup screen.

7. The BIOS does more tests on the system, including the memory count-up test which you see on the screen. The BIOS will generally display a text error message on the screen if it encounters an error at this point; these error messages and their explanations can be found in this part of the Troubleshooting Expert.

8. The BIOS performs a "system inventory" of sorts, doing more tests to determine what sort of hardware is in the system. Modern BIOSes have many automatic settings and will determine memory timing (for example) based on what kind of memory it finds. Many BIOSes can also dynamically set hard drive parameters and access modes, and will determine these at roughly this time. Some will display a message on the screen for each drive they detect and configure this way. The BIOS will also now search for and label logical devices (COM and LPT ports).

9. If the BIOS supports the Plug and Play standard, it will detect and configure Plug and Play devices at this time and display a message on the screen for each one it finds. See here for more details on how PnP detects devices and assigns resources.

10. The BIOS will display a summary screen about your system's configuration. Checking this page of data can be helpful in diagnosing setup problems, although it can be hard to see because sometimes it flashes on the screen very quickly before scrolling off the top.

11. The BIOS begins the search for a drive to boot from. Most modern BIOSes contain a setting that controls if the system should first try to boot from the floppy disk (A:) or first try the hard disk (C:). Some BIOSes will even let you boot from your CD-ROM drive or other devices, depending on the boot sequence BIOS setting.

12. Having identified its target boot drive, the BIOS looks for boot information to start the operating system boot process. If it is searching a hard disk, it looks for a master boot record at cylinder 0, head 0, sector 1 (the first sector on the disk); if it is searching a floppy disk, it looks at the same address on the floppy disk for a volume boot sector.

13. If it finds what it is looking for, the BIOS starts the process of booting the operating system, using the information in the boot sector. At this point, the code in the boot sector takes over from the BIOS. The DOS boot process is described in detail here. If the first device that the system tries (floppy, hard disk, etc.) is not found, the BIOS will then try the next device in the boot sequence, and continue until it finds a bootable device.

14. If no boot device at all can be found, the system will normally display an error message and then freeze up the system. What the error message is depends entirely on the BIOS, and can be anything from the rather clear "No boot device available" to the very cryptic "NO ROM BASIC - SYSTEM HALTED". This will also happen if you have a bootable hard disk partition but forget to set it active.

If by 'shut down' you mean 'suddenly and completely, totally loses power- fans, lights, everything.' Then it is a hardware problem, and a serious one at that.

If by 'shut down' you mean crashing, freezing, hanging, or shutting down as if you restarted to selected 'shut down' then it is a software problem. Reinstalling your OS will probably fix it. If you don't have one, I also suggest using a virus scanner as a virus could be the cause- but not usually.

If this is the first scenario, then it is a hardware failure. This sort of behavior typically occurs when some device that uses memory, or said memory, has failed. Why it may be occurring with multi-downloads only has to do with the way Windows handles buffering.

If you have only one or two smaller, or slower files being written, it is paged directly to the disk- IE, it writes to the harddrive as the file is downloaded, in real-time. If there is a lot of data moving quickly, or many files at once, it will use the Hard Drive's buffer- A small bit of RAM used just for 'storing' files until the harddrive can catch up. Usually this comes in 8MB, 16MB, and 32MB sizes. If this buffer is bad it can cause errors, but not typically power-loss. However an electrical flaw in the harddrive could trigger the Power Supply's safety shutdown procedure- Kill the power before something fries.

In the case of MANY files or very fast-loading files, actual RAM is used to store it until the Buffer can catch up and hold the rest. If your RAM is unstable, then crashes could occur at that time. Most commonly systems will appear stable under normal operation even when the RAM is bad, depending on what manner in which the RAM is bad. My memory, for example, is stable during everything, even gaming- however if I go into standby, hibernate, or data stays 'stored' for long periods of time, it will corrupt and cause crashes, bluescreens, errors, and even sudden power loss, or loss of video only. I fixed this by changing the DRAM timings so that it ran at 5-5-5-15-30 timings instead of 5-5-5-15-20 timings. Please note this IS an advanced step and you should ALWAYS contact the manufacturer BEFORE messing with timings. Improper timings can permanently damage your computer.

To test your RAM, try Memtest or running SiSoft SANDRA's tools. You'd be surprised how many people think their PC is fine but, in fact, has bad RAM that only causes problems 'once in a while'. That random crash to desktop in a game? May not be the game at all!

It may also be the power supply. If it's too weak and is being overloaded, the extra work of handling a full-throttle network transfer of multiple downloads may just push it over the edge- but this is unlikely. If your PSU is less than 2 years old and is 750 watt or more, you are probably fine. Otherwise, it can't hurt to test it- try reducing the power draw and see if the problems persist. Unplug things you aren't in immediate need of- Extra video cards, CD-ROM drives, anything USB, etc.

Finally, if it's the motherboard, it can also cause these problems. Failing motherboards can have all sorts of unusual symptoms and are very hard to pin down. Since it's the least replaceable component, the problems may persist even after you've tested every single other component. Bad motherboards rarely show up in benchmarks, memory tests, etc. And are only suspect once you've tested the CPU, RAM, and Hard Drive thoroughly (more than 8 hours -straight- nonstop testing at 100% load)

Bad motherboards are the third most common computer ailment, but the hardest to find and fix. Inexperienced technicians (which sadly, MANY are) will often replace devices that are known to cause such issues, but not actually fix the error. For example- a bad motherboard may show graphical errors and crashes in games. This makes you suspect the videocard, but may not in fact be the problem.

The most common components to fail in a PC:

1) Harddrive

2) Motherboard

3) Videocard

4) Power Supply

5) RAM

6) Other Peripherals (Soundcard, Network cards, modems, etc.)

7) CPU [Rarer for AMD than Intel, but even Intel CPUs almost never fail under normal conditions. This is due to Intels being clocked higher and producing more heat than AMD equivalents. A trade-off, you get more speed but lower life expectancy- only 4 years instead of 5. But who cares? In 4 years you'll probably have a new PC anyway.]

Hope this helps!
