Hello, I had my computer running for at least a year and now I can't get a signal to my monitor. I have tried multiple monitors and cables. I have tried multiple video cards. I tried moving the ram around and putting it back in. I tried taking out my motherboard's battery and putting it back in after a couple of minutes. Still I have no luck and no idea what to try next. Any ideas of what the problem could be, or how to fix it?
Edit: Also all the fans and lights appear to be working.
