So I'm in need of help, I am at the end of my rope and I've tried everything I can think of. My computer will turn on, fans running, lights turn on, a beep. Nothing is displayed on the monitor and the peripherals don't light up. I fixed it for a while by unplugging the hard drive from the sata port, and then plugging it back in. This no longer fixes the problem. I am hoping to find help here...I think maybe I need a new mother board, but I don't know. Please help me.
