New Build, Reboots out of the blue

[stillstanding]

I just built a new machine and loaded win xp pro on it with success. On two occasions while I was working in windows the computer shut off and rebooted. Windows says it recovered from a serious error. Anyone familiar with this problem?

-Thanks

You are going to want to see that error message. To keep it from automatically rebooting, right-click on My Computer, select Properties, then the Advanced tab, then the Settings button under Startup and Recovery. Uncheck "Automatically Restart".

Please post your system specs, including PSU model and specs.

When the reboot is complete the error message comes on screen and says it recovered from serious error, when I click more info it gives me a series of numbers.
