To Bleeping computer.. Using a house fan or table fan remove the side of the computer case and point the fan at the computer and allow it to cool. Turn the computer back on and see if you get better results. There could be other issues but this help with a cooling problem if there is one. Does the CPU have a fan on the heatsink and is it working? Is there allot of dust build up inside. If there is you should clean out the computer using a can of compressed air (available at most retailers that carry computer accessories) here is a tutorial
on cleaning your computer. The heatsink will get hot when the computer is operating but in most cases there is a fan on the heatsink to help keep it cooler. In some cases the processor can get very hot currently under low load my is at 37C or 98F. You can use SpeedFan
to monitor your CPU temperature when you get the computer running again.
Edit: Under mild load IE: Browsing messages on the forums my processor jumps to 65c and 149F its Overclocked by 4%
