I'd been having problems with my computer shutting down due to video card overheating, the temperature got to like 110+ grades Celsius while playing games (aion, tera, gw2) and would idle at around 70+ Celsius.
Anyways.. through reading the forums I'd tried dusting out the CPU fan/heatsink and graphics card, applied thermal paste between heatsink/CPU and also for heatsink on the graphics card. And it worked!! I was idling around 30 Celsius, games and other things between 60-70... but 2-3 weeks later now and its doing the same thing... Idling around 60-70 and hitting 110+ in games.
I don't understand why it would be fine for 2-3 weeks then suddenly start again
I'm not sure what i need to post for PC specs but..i think.. i has..
Antec Basiq 550w PSU
ATI Radeon HD 4670
AMD Athlon 64 X2 dual core 6000+
