I had a problem with a game recently (blue screening and crashes) so i updated my video card BIOS. Not only did this not fix the problem but it started others in games that used to be reliable but have now become nightmares. I bluescreen/ crash to desktop frequently in games i used to be able to play for hours with out any problem, and this problem has only started since I updated my Video card BIOS. So my question is how do I revert to previous working BIOS for my video card, and one other problem is I do not know what version of BIOS i was running before-hand, I just upgraded. Any help is appreciated.
