I have a problem where whenever I try to play games like CS, Dota 2, etc. It just shut downs 2-5 minutes into the game. Not sure what's broken in my PC but I noticed that if my PC makes a fairly loud fan noise, it wont shut down and the problem doesn't show up. But if my PC makes small fan noise it just shut downs whenever I try to play. IIRC, last time I checked my temp it was around 80-85C.
My specs :
Intel Core I3 - 4160 3.60Ghz
8GB DDR3
NVIDIA Geforce GTX 560
I know it sounds horrible but it used to run games like CS, Dota 2, etc at 100-200 FPS.
My question is what is broken in my PC and what part should I replace in my PC, or is my GPU hella bad?
