Gaming PC Computer Case w/ASUS P4PE Motherboard Parts or Repair
The computer was opened and thoroughly cleaned.  When I applied power, the green light on the motherboard lights up with no beeping sound and there was nothing shown on the monitor.  My guess, and I am guessing, is a bad CPU that was probably overclocked.  Since I could not get anything on the monitor, and I don't want to remove the heat sink, the CPU is unknown.  All the internal drives are thus untested.  The case is an unknown gaming case.  All the lights work on it, even the ones on the front.
I am selling this unit as-is with no returns.
