um well does it just reboot itself or do you have to manuallly turn it off. My best guess is check and make sure the heatsink (the part cooling your cpu) is firmly attached. Usually the stock ones have these plastic turn tightening things, just wiggle those and well if they wiggle then you should get them tight.

Repeatedly press F8 before windows begins to load so you can see if you can enter safe mode.
