Disconnect all cables from the PC and take it outside. Remove the side panel. Blow all the dust from the unit with compressed air. Pay special attention to the cooling fans and the heat sink on the processor. Do not touch any components inside the PC without first touching the outside of the case to discharge any static electricity. Check to make sure the fan on the processor is securely in place. This should solve the problem. You need to do this every 6 months.
