Hello Following an attempt to install win 10 I found myself with a bios problem. I had to try to fix it and on reboot nothing works. The pc turns on with 1 long and 2 short beeps (graphics problems I think?) my card runs and the fans but nothing on the screen. The latter is new (Medion) and everything was working properly before rebooting. So I tried to reset the bios by removing the battery overnight and disconnecting the cable, but it was still the same (black screen and 3 beeps all the time). I don't think my original graphics card (GF GTX 650) is burnt? But maybe it's disabled in the bios that I can't restart. Is there another way to reset it? with jumper?
