So the only way that I can test a CPU is with a motherboard, which may very well fry the motherboard. Hmmm... seems like there would be a better method.

Very uncommon for CPU's to be bad but it can happen.
Could you give a bit more info. When you start the computer what happens. Does the cpu fan come on is there any led power indication on the board or front panel of the case showing. Are all the power plugs connected properly, try reseating them.
Is the square 12v plug connected to the board.
Have you tried another Power supply.
IS the monitor a known working monitor.
Have you tried a PCI video card, sometimes the onboard isn't set to be the first display in the bios(most times it is automatically changed when a card is used.)
If you suspect the CPU, try another CPU in the board, don't use the bad CPU on another board as it may kill another board.
I have the motherbaord out on a wooden bench so that I can test it seperately from everything else. I have a known good power supply plugged into a brand new motherboard that was ordered from emachine parts. The only thing that I am using from the original computer is the CPU. The old motherboard was fried from a lightning strike. When I use a screw driver to short out the power connector the CPU fan turns on. The LED on the motherboard is always on when I have power to the power supply, but I never get any video, the light on the monitor stays yellow. I know that the monitor works. I haven't tested a PCI Video card but I have cleared the BIOS and taken out the CMOS battery. I will be testing a PCI video card soon hopefully.

Hello accrain:
A dead CPU equals a dead board - no error messages.
You can check the CPU in another motherboard with the same type of CPU. It's unlikely but some bad CPUs can wreck motherboards - cracked supstrate dies will short the power circuits out and fry the VRM.
You would be best served trying a known good CPU.
