I've been getting some random shutdowns while playing hardware intensive games (like crysis) lately. The computer simply shuts down and I have to wait a while before it can be turned on again. I've been monitoring the temperature of my components and here are the results (all at full load):
motherboard (Gigabyte GA-MA780G-UD3H) - between 45 and 50°C
CPU (AMD phenom II 710, overclocked @ 3.2ghz) - between 40 and 45°C
GFX card (geforce gtx 260) - between 65 and 75°C
I did some research on temperatures for these three and apparently they're all ok. So I'm wondering if anyone could tell me what else could be the reason for this kind of PC "behavior"?
