I recently switched my graphics card from a Nvidia 9800GT to an Evga GTX760. After the switch, my computer would restart every time I click the shutdown button. This also happens when I click on sleep. It would just wake up immediately. I'm not sure if this has to do with the graphics card change, but it only happened after I switched the cards.

Another problem that I'm having is that the computer restarts itself randomly when I'm gaming or watching a video on youtube. It restarts at around 10 min of gaming or when I have multiple tabs of youtube open. I've checked memory with memtest and passed 5x with no problems. When I run HotCPUtester, the computer crashes and restarts without warning.

All my drivers are updated and the temperatures seem pretty normal. (29C Idle and 55C on load) for GPU and CPU.

Specs:
CPU:AMD Phenom II X4 965 Black Edition
Motherboard: Gigabyte GA-870A-USB3
GPU: Evga GTX760
PSU: Corsair TX650
RAM: 8GB GSkill DDR3

Thank you very much for your help.
