My computer died last weekend. I want to wait until Haswell comes out next year before replacing it. I have an old XP desktop that I've powered on to use in the meantime. The XP boots and works just fine. So I decided to take my 8800GT card from the dead computer and plug it into the XP.
When I turn it on, it beeps in a long constant single beep that never ends. I can go into the bios, but I fear keeping the computer on too long while it's singing, so I just shut it off. If I remove the graphics card and go back to the onboard video, it works just fine with no beeps.
For reference, the XP computer (Cisnet) uses an MSI motherboard. It has a PCI-E slot and also SATA ports. My dead computer is a Q6700 Kentsfield with an Intel DG33TL motherboard.
I believe that the problem might be the power supply, but I'm not certain. The computer only beeps when the graphics card is plugged in. Any ideas?
