Random restars

[snapsh00t3r]

Hi, recently i had some problems with BIOS settings(i changed to "Top performance" but for some reason it was not responding after the restart...so i removed the CMOS battery to clean BIOS) since then my comp restarts randomly(not many times, 2/week).Is it bios or something wrong with registry? i also chack my CPU temp and is fine, and event log only show a "SERVICE CONTROL MANAGER ERROR"..ANY HELP?
(I am using windows XP SP2)

Set your BIOS back to default settings

Right click My computer>>properties>>advanced>>Settings

Uncheck Automatic Restart.

Instead of restarting next time, It will just blue screen. Record that error and post

also check to see if there is an update for your bios
