Bizarre Video Problem

Ok. This one's a longshot, but I'm hoping that someone will be able to offer some ideas on what the answer to my problem is.

I have a problem with my computer where the video will go completely. If I loosen the screws on the front panel of the box and move the box around, I can get the video to come up. If I change the angle of the box at all, it goes out again.

I actually managed to get the video to work consistently with the box sitting up normally for a while, but when I decided to put the box together again, I lost video again.

It's not the video card. I've tried two seperate video cards, and they both had the same problem.

It's not the monitor. I've hooked the monitor up to my laptop and it works fine.

I'm betting that it's a short somewhere, or a loose wire, or something like that. I've looked over everything, and I can't see what's going on.

Has anyone ever seen anything like this before?

 

Is this a PCI vid card?... do other PCI devices work fine?

 

1. motherboard touching case(like under bottom of motherboard)
2. faulty slot your vid card is in, try a dif one
3. um a little man inside your computer is playing tricks on you

really it shouldnt be that hard to fix since it does actually come on, you just gotta put more effort in to finding that loose wire/slot/ic/board/whatever just keep on messin with it.
im sure you can handle it solo

Thanks for the help guys. It's a PCI card, and yes. Other PCI devices work fine. I don't think it's a bad slot, because I've tried two different video cards in several different slots, and I have the same problem.

I've also tried jiggling all the wires and it doesn't do anything. It doesn't look like the motherboard is touching the case, but I guess I'll have to investigate more. Maybe tonight I'll take everything out of the case and put it back in one thing at a time to try and track down the problem...
