I recently put together a new system and was pulling parts from my other computer to put in the new system. When I went to put back in the old video card, I was in for a shock. When I went to boot up, there was no video signal. What happened? I checked the old card on my new system and it worked. I also tried my new Banshee card (PCI) in the old computer (it worked in there before) but nothing now. I have tried all the different PCI slots and rechecked each connection. I cannot even boot to get into the bios. Any help would be appreciated. Thanks
