Motherboard go bad?
I was playing a game on my computer when all of a sudden the computer froze up ( didnt go black or anything, just froze) and then stated making a annoying buzzing sound. When i shut it off and tried to restart, the annoying buzzing sound was still there and wouldnt go past the motherboard post screen. I tried retarting over a few times and when it did get past the post screen it hung up in DOS and said that there was no keyboard found, and to press F! but was froze on that screen. When it goes to DOS and freezes it doesnt buzz, but when it goes to post screen and freezes it buzzes. I tried to hear where the buzzing was comming from and sounds like its comming from the motherboard speaker. Any ideas what it might be?
