Im trying to use my older video card which i got about 6 months ago.Its a 7600 series Radeon version 2.0 i think. When i installed the video card it gives 6 beeps and blank screen. I changed out the powersupply to 500Ws. I know the card works because i got it tested. I was told that it might be the bios but i dont see and update anywhere for bios.
