I removed all RAM and plugged it in. Nothing. When I press the power button on front, same as always, the fans spin once and stop. (The light on the button does not stay on. It immediately goes out. I direct wired it earlier on the MB and the same thing happened.) I then disconnected the cable from the MB and direct wired it (green to blk) and plugged in again. Same as always, the fan on the PSU cuts on and one of the disc drives powers up, but the fans in the computer do not turn on or the HD. Don't see a way to check the beep code when it won't power up.
