Here is where i found out about XP rebooting. im posting this because no one acknowledged my post

and i want to feel clever.
"Windows 2000 and Windows XP have a feature, that is enabled by default, which automatically reboots the computer when a BSOD ("Blue Screen of Death") is encountered. If your computer is automatically rebooting disabling this feature will allow to see the error message on the BSOD.
To disable this feature, open System Properties by right clicking on My Computer and selecting Properties. Alternatively you can hold down the Windows key on your keyboard and press Pause/Break.
Once you have System Properties open click on the Advanced tab, then click on the Startup and Recovery button at the bottom. When the Startup and Recovery panel opens simply uncheck Automatically Reboot. Then select OK twice. Now the next time your computer encounters the problem you will be presented with a screen that will help you track down the issue you are having.
For help in diagnosing the error message you may want to reference Demystifying the 'Blue Screen of Death' in the TechNet section of Microsoft's website. " - Psychoholic

though im not dismissing that it might be the power supply. it just seems that if he sees a pattern for when it crashes (like closing a bunch of windows), then it is probably a software issue.
