No video - but cards work

[imported_Septimus]

Here's what happened:

Building a new system. Cannibalized existing system, which was an AMD 4200+, 2GB RAM, on an ASUS A8N-SLI board with an eVGA 7900 KO PCI-e card.

New system isn't important, turned out to have a bad motherboard. Put everything back in the old system. It boots (even loads Windows - I can remote in to it) but there is no video out.

My question is: Can a DVI cable be the source of this problem, or is it possible for a motherboard PCI-e slot to be bad but not cause a video error POST failure/beep code?

I am replacing the DVI cable tomorrow (from Newegg - in-store here in NYC they're $60!!!) but am curious if I should investigate the board/PCI-e slot as being problematic as well.

Forgot to mention - took the video cards (I tried two, the 7900 and a 6200) to the local computer shop and had them checked out and they work.

Have you tried using a VGA cable?

Odd, but I had a problem a while back where the DVI stopped working. After talking to Viewsonic tech, they suggested that I unplug the pc and monitor from the wall/surge protector. Then after about 10 seconds plug them in again. Turn on the monitor first and then the pc. Shockingly it worked. I guess it was king of like sometimes having to power cycle the modem & router.:Q

Holy logjams, batman, that did it. Viewsonic monitor too.

I'd checked out every single component and was starting to think I didn't have the touch anymore. It never occured to me to do that - I'd unplugged the monitor for a second but not left it unplugged.

You just saved me a trip downtown to buy more replacement components I don't need! Thank you!
