Hi,

 

Try this procedure:

Unplug the PC and open it up. Clean out all the dust. Carefully remove and replace all the cables going to the motherboard one at a time. Do the same for the memory dimms and the video and sound cards if you have any.  You might want to buy a can of compressed air to blow the dust out of the CPU heat sink and video card.  Plug your PC back in and give it a go.

 

If the above doesn't help then try the following procedure and see if you can isolate the problem.  Don't skip any steps.
