Open your case, check your fan to make sure it is spinning. If it is rattling or not spinning fast replace it. While holding the case frame, touch the side of the heatsink(not the fan). If it is so hot you cannot stand to hold your hand on it, the heatsink is too small, or clogged up with lint/dirt etc.
I have to remove my Heatink and fan from the case, remove the 4 screws attaching the fan and heatsink together. I run warm water thru the fins and clean out every bit of the lint. I re-attach the fan and re-install it onto the motherboard. This has solved the problem of overheating CPU and crashing in EQ1 and now in EQ2.
If you are not competent in working with PC's have a friend help or take it to a repair shop. You can permanently damage the CPU if you fail to plug the fan into power, shock the CPU with ESD, or impropperly mount the heatsink to the CPU.
Also you can do the same with compressed air can if you can find one at a computer store. You dont have to remove anything.
Hope this helps.
