Spontaneous Reboots on XP! Help!

[Lyoness]

I am running WinXP Pro on a P3-600MHz computer with 512Mb of RAM and a 70GB Hard drive.

For no reason at all, my computer reboots all of a sudden! I could be doing different things and it just reboots. Once it starts again I choose to send the report to microsoft and I've kept track of most of the times it happens (I must have like over 15 entries already on the microsoft site) and it usally says that they don't know why it's happening but it could be a device driver problem.

Does anyone know what is going on??

Thanks
Lyoness

Go here and uncheck the box called Automatically Restart.

Right click My Computer/Properties/Advanced/Settings for Startup and Recovery.

The next time it happens you will see a blue screen with an error on it; and it should give you a hint what is causing it.
