I royally messed up and I have no idea what I was thinking but I tried to flash my bios to increase the voltage and get more power out of my card.... It was a huge mistake because now when I turn on my computer the colours are completely jacked and there are lines everywhere... I have no idea how to fix it. I tried flashing the bios with all 4 of the bios on this website for asus 680's and none of them fixed the issue. I should also mention that I did the flash through a bootable usb stick and still no deal... Can anyone out there please send me the correct bios or tell me what to do to fix this 500 dollar mistake? It would mean everything to me as I need my computer for school.... I have an Asus GTX 680 DC20 2gig card. If you need to know anything else please feel free to ask. Thank you all ind advance.
