Hello, I have a serious problem, my motherboard isn't working. It still turns on, the fans run, hard drives starts, but nothing appears on the screen. I'm posting this message from the same computer, but with a different motherboard (A really old one), I know the motherboard cant be fried, or it wouldn't start up at all, I'm not really the Mr.Know it all when it comes to computer hardware, but i do know the basics (If you call changing motherboards basic), I think the problem all together here is, it wont POST. Please help!
