When I hit power, all external fans power up, but nothing comes up on the monitor. Sometimes the video card fan will spin, but it's very slow and will sometimes stop.
When I plug in the 4 prong CPU 1 power, the CPU fan won't spin, but the video card will. When I plug in the 4 prong CPU 2 plug, the CPU fan spins, but the video card fan won't spin. (By CPU 1 and 2, I mean there are two different plugs from my PSU that I've tried).
I've tried two different video cards. One we know for sure works. No matter what, we never get video on the monitor.
We're pretty sure this is a power supply problem, but before cash starts being thrown around, we'd like to make sure.
I've cleaned/dusted everything, set and reset the video card(s), RAM, tried one stick of RAM, different RAM slots... always get the same results.
