I suspect that the power supply is faulty, though it could be a problem with the motherboard as well. You need some diagnostic tools to check the system board and power supply. This is a free one that has good reviews (self-booting CD image): http://www.hiren.info/pages/bootcd, and here is a link to the download image: http://www.hirensbootcd.org/files/Hirens.BootCD.15.1.zip

I just downloaded and burnt the CD and booted it to explore it a bit. It is an awesome set of tools. One that is on the mini-xp image is called s&mstress which will stress test the system CPU, power supply, hard drives and controllers, etc. That would probably help determine if your problem is the power supply, or something else.

If your computer crashes then there is a problem in motherboard just change it and see the differnce
