Nothing showing up on monitor... Not even "no signal" message

[Mikepsyche]

Ok, so if anyone has any ideas let me know.

Symptoms -

1. Nothing showing up on monitor, no signal
2. No POST Beep
3. Phase LED and DDR LED lights showing on motherboard

If you have access to a POST card I would try it, for it is worth a shot.


BTW have you tried the original video cable that did work with the monitor?

A POST card?

Yeah, I tried with the original cable, no difference. I hope it's the video card, at least I have a warranty on it.

EDIT: I looked up POST cards, and there already is a built-in system like that for the UD5. I should have said what the code was, but I didn't think to. It's displaying the code "C1" now. Under normal conditions it displays the code "FF". Not sure what either code means though.

- Maybe I'll try disconnecting the video card completely and turning the computer on. Of course I'd get no signal, but assuming the problem is the video card, I'd get a POST beep and everything.

-Hmm, just looked up the "C1" code. Eventually found it on some other forums - apparently C1 is something to do with memory - "C1 Detect memory, Auto-detection of DRAM size, type and ECC, Auto-detection of L2 cache"
