I don't understand how that could be the problem, especially since you have a video card. Are you sure they said CPU and not GPU? Drivers instead of bios? Be very sure first and try updating the drivers for your video card first. But if you're going to update the bios go with the newest ones that aren't beta. In this case that would be the FC version. Do you know how to flash your bios? Be very careful when doing so because if it or you mess up you could end up with a brick for a computer.
