The inebriated numpty was me last night You live and learn! Anyway, Gigabyte didn't help as the selections were a bit confusing. So I have the incorrect BIOS on my card and the problem is that my computer will not boot with this card in the computer. I can boot into windows fine without the card in by using the integrated graphics chip, however if the card is in the computer will not post, there is simply a flashing underscore in the top left corner. Now clearly if I can get the computer running I can reinstall the old BIOS (I was sober enough to make a backup) but its getting the computer running with the graphics card plugged in that is the problem. Any ideas? And thanks for any help.
