|I BIOS update for a problem that is not specifically listed for a fix on the BIOS update page, is generally a bad idea. There is always the chance that a BIOS update can go badly and render the machine useless.|
First, delete your current graphics driver from Device Manager. Then make sure that the graphics cad is plugged into the correct slot, try reseating it again to be sure it is fully inserted, make sure that all connectors are still fully plugged in after you are finished working in your system, and try booting to Safe Mode and update your graphics driver if you can get that far, or try booting into your BIOS to see if it is working at all.
It is possible that you got a bad graphics card or one damaged in shipping.
You have to be a little bit crazy to keep you from going insane.
