|Open the case. On the motherboard, you should see a battery (like a large watch battery). Somewhere near the battery there will be a set of 3 jumpers with the middle one jumpered to one of the outer ones. Switch the jumper to the middle pin and the other outer pin (the one not used before). Wait a few minutes (scratch your bum, kick the dog, whatever passes time), then switch the jumper back. What you just did, was reset the BIOS to default values, so any erronous data relating to the card install will be gone.|
If you can't find the jumper and your CMOS battery (mentioned above) isn't soldered in, you can take the battery out for a few minutes. Replace the battery and you should be good to go.
After a BIOS reset, you should boot up and press whichever key you need to enter the BIOS (system setup) utility (usually F2, F1, Del, etc). Make sure all your drives (HDD, CD/DVD, Floppy, etc) are being detected. Set the time and date (if needed), then move on to memory settings and make sure your ram is reported correctly. You should see a setting somewhere that says "Load Optimal Defaults", or similar words. Chose this setting then save and exit the BIOS (F10 key on my machine).
Before installing that card, I'd be inclined to test it out in another (expendable) computer. It may be a fault with the card that gave the BIOS corrupted data.
Assuming that's a PCI card, do you have another empty slot you can use? There may be a problem with one (or more) of the tiny contacts in the PCI slot.
Just tossing some thoughts about that might prevent the same problem occurring again. No point resetting the BIOS just to have it happen again.
IMPORTANT: Before you touch the inside of your computer, be sure to ground yourself to lessen the risk of static charge damaging your hardware. Ground yourself by touching a metal part of the case (not a painted surface). You only need to touch it for a second or so. The static discharge happens the moment you make contact and the small (but deadly to computers) static charge is gone.
A good idea, when opening the case for any reason, is to purchase a can or two of compressed air to blow any dust out of the case and components. Pay particular attention to the heatsink/s on the CPU/s. Dust build-up on the heatsink can make it inefficient at dissipating heat. This can lead to a damaged CPU (not cheap), and is a relatively cheap and simple maintainence task.
Hope this helps.
