Why computer sometimes failed?

Answer 1

I rarely see a computer fail completely. The fact is that a computer is a collection of devices all working together to perform the tasks you assign.

Computers have several critical hardware components:

• Motherboard
• RAM
• ROM
• CPU
• Power Supply
• Hard Drive
• Graphics Card*

*A graphics card is not absolutely essential for a computer's operation as the CPU can perform the same tasks however some monitors' minimum resolutions are too large for the CPU to handle and require a dedicated graphics card or an integrated graphics chip.

The failure of any of these devices can cause the computer to shutdown (perhaps even permanently).

In the event of a hardware failure the failed component must either be repaired or replaced. It should be noted however that computer's don't always fail due to hardware failures, sometimes the software can cause failures. Software failures can be anything from a simple driver malfunction to the loss of the computers master file table. In the event of a software failure, you can still recover your computer simply by reformating the drive and reinstalling the operating system. If you use the windows platform you can try booting up in safe mode by pressing F8 at the startup screen and then using system restore to restore your computer to a state before it failed. Please note that in most cases you will be able to recover your data in the event of a software failure. In order to recover the data you can use a live disk (assuming your computer has a CD/DVD drive) to boot up your computer and then copy the data. More complicated options are also available but i'd rather not discuss them as they are not within the scope of this question.

You should also note that sometimes the computers hardware can fail for an instant (probably a stray electron :) ), this will cause a system crash and thus force you to restart the system.

There is always the possibility that the system shut it self down to protect itself and didn't actually have any failure of any kind. This could be the result of overheating due to dust build up or a power irregularity.

Answer 2

It sometime fail because the computer need the people to put the answer or need people to control them. The reason why it fail, it is because the owner put wrongly

Answer 3

Because it is only made by man...There's no creature on earth that cannot fail...All of us fails...Also, machines have their failures because they are not made perfectly...

..?..

Answer 4

because it cant think wat can people can did ..and sometimes only people can answer wat a computer only does ..it cant answer corectly if a user didnt help ..
