I have a desktop computer here that can't boot after a long power outage (it was behind a UPS/surge protector though). It won't boot now and is giving 1 long beep and 2 short ones. The motherboard is an ASUS M2NBP-VM CSM, which uses an Award BIOS. From searching online, places say that 1 long beep and two short ones mean that the graphics card isn't working. But this motherboard has onboard graphics, which is what I'm using. There are no other graphics cards in the system. Although I tried putting one in to see if that resolved the issue, which it didn't.
I also tried clearing the BIOS to see if some issue there needed to be reset. Nothing. I checked the motherboard for obvious signs of being fried and can't find anything wrong. Any ideas as to how to resolve this issue? Thanks.
