Hello guys, I bought a graphics card a month ago. After a while, I realized that it makes my computer restart when I'm playing games. I get no error, no blue screen, no nothing. When I'm playing(when GPU load is 90% or more), the computer just closes down and starts again. The graphics card model is ASUS GTX 770 2 GB DirectCU II I tried to run some stress tests on my graphics card with Furmark and it makes my computer restart again. So I took my GPU and power supply and went to a friend of mine. His computer was kind of old which has a 500W PSU. We changed it with mine. We got no error, no restarts. So I know that, it's not the GPU and PSU. My Specs: MSI Z87 G45 Gaming MBO Intel I7 4770K Processor 16 GB Corsair 1600 Mhz Ram You know the GPU 700W PSU My Friend's Computer Specs(In case you need it): Gigabyte GA-MA74GM-S2H Mobo AMD Athlon II X2 240 3 GB DDR2 Ram If you guys have any suggestions how to solve this problem, I'd really appreciate it. Thanks in advance.
