Sort of a followup to this question. The mobo's getting power, the lights are on. The GPU fan is spinning (it doesn't use auxiliary power, it's only connected to the mobo).
I'm not getting any video signal, and it's not the video card (nor monitor) that's faulty, so I'm suspecting mobo or CPU (possibly RAM?) and I'm trying to pinpoint which part is at fault.
Is the motherboard a candidate for being broken or is it not very likely if it's getting power and powering other components? The CPU fan is getting power as well.
