Computer suddenly shuts down

[GX1_Man]

A counterfeit XP and it doesn't run? How unusual.

www.memtest86.com allows you to download a file and create a bootable floppy or a bootable CD. Just boot with that in there and run the test on each RAM for an hour or so, then all together.

Here's some info on Event Viewer from the company you pirated the software from:

Did you check your temps? How about removing a side panel and blowing a fan directly in there?

Here's some good reading:

You're looking for the reason the machine shut down, if it is shown. Just read:

This is like herding cats.

1) Test your RAM.
2) Try the fan on the open case.
3) Disable Auto Reboot on System Failure & check your Event Viewer.
