Whenever i try to start my computer, the fans and lights turn on, but nothing else. The motherboard dosn't even beep like it use to. I know somthing is wrong inside, my brother took some memory out of it and i started it up and smelt somthing burning. It smelt like it came from the CPU but i'm not certain, and don't want to waste the money on it if thats not the problem. If you could please help me, i would be very thankful.
