I have recently got a new graphics card a GTX 970 since I have had it (4 days) I have had 3 instances where I can smell a sort of smokey smell and my pc would just turn off not shut down but switch off in the middle of gaming. I am only assuming it's my graphics card because it didn't happen before I got it but again any help is appreciated. My specs are EVGA GTX 970, 600 watt PSU, i7 4770, Windows 7 and a Gigabyte mother board with a pci 2. I really don't know what to do. Edit: PC will currently not turn on.......
