Emoster won't boot up

My emonster 600 was working fine, I turned on the PC and the light keep blinking fast and no signal to the monitor. The cooling fans are running but it appears nothing else is. I unplugged the machine waited and plugged it back into the outlet, it immediately started the same thing without touching the power button. I tested the PSU, I had 10.5 volts on the 12 volt side and 3.7 on the 5 volt side. Do I need a new power supply or should I try resetting the CMOS? Thanks for any help.
