Hi guys, I'm having problems with my pc overheating pretty much any time, with or without major programmes running. I have got several fans inside, and quite sure they are all blowing in and out for maximum airflow. I have resorted to using a normal household fan, to cool the pc down. Obviously this is inconvenient, and was hoping you guys could maybe help me with possible solutions or things to check. With this external fan the lag does stop. So obviously it is heat related. I just don't know whether it is the CPU causing the major lag, or graphics card. They both run quite high without the external fan on. I'm using an AMD dual core 6000+ Cpu, with an xfx 8800Gtx. I'm am also using windows vista ultimate. I have loaded one of those gadgets to tell me cpu and ram usage, and have noticed that when it lags like it does, the usage for both, goes extremely high, to the high 90%
