Power Supplies

[gaf at blu.org (Jerry Feldman)]

It is definitely not as I am getting some power. All the fans are running, 
so I can assume the 5V power is ok. The HD itself is initializing on power 
on. Beyond that nothing. 
My plan is to pull the power supply with the bad fan out of my wife's old 
computer, and plug it into the bad PC. That will tell me that the power 
supply works. Again, from my testing so far, it appears to be either the 
mobo or the CPU. I have an older motherboard with a CPU that I replaced 
last year. I may be able to swap that in tonight.
