I removed everything from the motherboard and even tried another CPU
that used to run on that same motherboard.  No luck.  I can't test the
power supply in my P3 router because the CPU power plug is different.

I should have said before that every couple times I try to turn it on,
the CPU fan spins about 2% of a full rotation and some of the LEDs
along the back light up for a second.

Would you guys say it is most likely the motherboard at this point?
