Pc reboots after loading

[paul noble]

Hi
Can anyone help?
My PC reboots after loading.. can it be a driver or something?
If I start the PC in safe mode it is fine or if I do not logon and just leave it sitting there with the logon box displayed it is OK.
Any clues anyone?

sounds like a driver issue,..pls list you system specs(hardware/OS)

is this the first time you encountered this?
