The system itself is only year old. I have a 600 watt PSU Enermax. It was doing fine untill now. It wont even reconize the keyboard or anything like that. Everything spins up when I power on. When I turn it on I get the short beep, after that just sits at the platinum screen and doesn't do anything. I took the memory out, turned it on and I get the beep code of no memory. Video cards are fine. HDD works CPU comes up fine. I don't know what I should do.
