These past few weeks my computer has been overheating very easily. I'm not talking about just temperature readings. It sounds like a jet engine and it heats up my room. I have no idea what is going on. Last night I cleaned every bit of dust out and it's STILL doing it.
Specs (not the best in the world)
nVidia GeForce 7600 GS
2 GB ram 266 MHz
Pentium 4 3.6 GHz (2 CPUs)
250 GB hard disk
and it's all put inside of a Dell Optiplex GX260 case/motherboard. The reason it's in there is because I used to have a Core 2 Duo until I overclocked and it ruined the motherboard as well as the CPU.
I'm thinking it's the case but I am not 100% sure
