Ok my system recently just stopped booting up in the morning. I powers on and runs thru BIOS then blank screen. No HDD lights no noise nothing.Takes a few tries powering on for it to work. I have 2 fans in it (LED) and the one in the window moves slow and the other is fine. I unplugged both fans and 1 cdrom and system boots fine. Is there a way to test a PS to see if power is falling off?
