I ran into a power supply failure that also took out the motherboard and 
mouse.

I figured the likely failures in order of probability is: 1. power supply; 2.motherboard; 3. CPU. So I tried another power supply - no success. Then I replaced the motherboard - power light and drive light come on but the HDD doesn't run up. Also replaced the memory. Replaced the HDD, still no success.  So the only thing left that I can think of is the CPU.  Is there something else I should check out? I realize this may be an exercise in futility, but it's a learning experience.
