DIY Hardware Failure - Follow Up

The PC is finally repaired. The final result is that the CPU and the motherboard were both bad. I received the CPU from my supplier and plugged it in and found that the motherboard would not boot successfully. So I plugged in the CPU in my known to be good PC and everything worked fine. So I ordered a new motherboard and put it together using the CPU from the 'good' PC. Everything is fine now.
