I've had my Gigabyte motherboard for almost two years now and it just started this beeping. I know it means a graphics card issue, but what I don't understand is what could be my problem exactly. My computer tower fans aren't running when I turn on the computer, so I was thinking that maybe I don't have enough power getting through to some of the parts of my motherboard. The other option was that my motherboard is half shot. What is your opinion? Is it more likely to be my power output or my motherboard?
