Greetings Listers, I am dealing with a system that won't post, and give nothing but a blank screen. I have tried disconnecting everything, and I still do not get any display or post beeps. When the IDE cables are left connected, the HDD light stays lit solid from the moment the machine is powered up; if the cables are disconnected, the light stays out. Also tried a different video card. The CPU fan does power up. I have heard of some issues with burned transistors and leaking capacitors on these boards, but my inspection reveals nothing along these lines. Also, I have done a pin-by-pin voltage check of the power supply, and all seems well. Was going to try a BIOS update out of desparation, but the machine doesn't even seek it's floppy drive to find a boot disk. Any insight or suggestions would be greatly appreciated.
