My brother has a 7600 GT for about 2 year now.It didin't give him much trouble except now.The 7600 now heats up pretty quickly and the games,which used to run quite well,now start to run in slow-mo.Also after running for about 20-30 mins the fan of gpu stops suddenly and doesn't start until system is restrated.The GPU is getting heated up pretty quickly now.He has a 350W power supply with Inel C2D and @ GB RAM.
have you tried cleaning the card ? Dust will cause it to heat up and spot the fan cooling properly. It does sound like you either need a new fan or card though. The slow mo thing is probably the memory over heating.
Um i was talking about the memory on the Graphics card, not the system memory. As far as taking the card apart i think it would be easier if you googled a guide from the internet. Its not that i dont want to help its just that by the time i had typed it all out you would have read the online guide and taken the card apart cleaned it and put it back together again
Computer/electronics stores sell cans of `compressed air` which are supposed to be quite good, just squirt it into the heatsink AGAINST THE NORMAL AIRFLOW DIRECTION I.E. into the exhaust.
Just do n`t do it indoors. Or towards your/someone elses face. Or against the wind.
