- 1). Unplug the computer. Open the computer case. Ground yourself by holding the metal part of the case. Unplug the power source for the fan sitting atop the processor. Remove any screws that hold the heatsink and fan. Unlatch the clips on the side of the heatsink and fan and remove.
- 2). Touch the processor. If it is too hot for you to keep your finger on the processor, the processor may be overheating.
- 3). Check to see that the processor is properly faceted to the socket. If any of the hundreds of pins that fit into a socket on the motherboard are bent or not seated properly, the computer will not function.
- 4). Check the BIOS for proper processor settings. If the BIOS is set to the wrong processor speed, the hardware can overheat and cause problems with the computer. Check that the BIOS displays the right processor speed and type when booting the computer.
- 5). Swap out a good processor with the one having issues, if you have a spare processor that is compatible with the motherboard. If the computer runs fine with the other processor, then replace the processor.
- 6). Check with the motherboard manufacturer to ensure that a new processor you have bought or may buy is compatible. Most motherboard manufacturers list compatibility specifications on the corporate website.
