Check your plug that runs in to the back power source. It may have come loose a bit. Make sure it is plugged in snug. What are the specs of the pc, motherboard, gpu, psu, etc?

I would give the computer a good cleaning again. Pull the memory and clean the slots, and any other slots you can see. Clean any dust you can see on the front and back of the motherboard. Take a look inside your psu and see if there is a lot of dust inside of it. Any and all fans should be cleaned especial attention given to the cpu cooling fan. I think you may just be experiencing electrical arcing due to dust. See if this helps.
