PCI Express slot no longer responding to Hardware - Help please!
I have an Optiplex GX620, which has run wonderfully for 2 years with no problems. I upgraded to PowerColor's HD 2400 256mb PCI Express card a few months ago, again with no problems. As I was carefully dinking about in my case yesterday, (with the computer on), I apparently touched something, and the display suddenly gave-out; the touch was as delicate as is imaginable.
Thinking I had fried the card, I tried to install the old PEG which was working just fine when I made the upgrade, and it didn't work either. I should note that with either of these cards, the computer makes its start-up as usual, as I can tell from the sounds of the boot sequence. There is no other indication that anything is wrong, and that's with the card in, and the monitor plugged-in.
I have a lot of experience installing and upgrading hardware, but no real practical experience troubleshooting the motherboard or figuring-out where to look to diagnose a problem like this.
I wonder, is the PEG slot fried? Why is the computer operating without a problem with this condition? Is there a default setting in BIOS that took-over and disabled the slot? Is this fixable?
In BIOS, it doesn't give any indication that there is anything wrong with the slot either. The PCI menu shows all of the slots, and the PEG is simply labeled empty.
Also, if there is no way to fix the slot, can anyone recommend a good PCI gaming card for under $200?
Any help with this is greatly appreciated! Thank you, in advance.
