Hi, over the past day my pc has been restarting its self when I play a couple of games (dead rising 3 and dirt 3) I play for about 5 mins and its just restarts my system. Ive looked in my pc and noticed only one fan spins on my XFX 7970. This is the case until on MSI afterburner I crank up the fan speed to 75%. However I was playing dota 2 for a solid two hours yesterday too and it worked perfectly. I have cleaned out my pc with compressed air so there is no dust, and only one fan is still spinning. Is this the cause of my random restarts? or is my card just broken and not the cause of this?
