My computer was running fine than it just froze, I could not do a regular restart or shutdown, so I just held the power button and shut it down. Now it wil not turn on, the power button just turns orange and green for like a half a second than stops. For like a second, my graphics card fan will spin, the green and orange lights go on for like 1 second. Then everything stops. Anyone know why? I am guessing the Power supply would be the problem. I tried unplugging everything, and just try turning it on with the main power cord, but that did not work at all, same results.
