I have a pc I am having trouble with. I unplugged everything but hard drive, 3 1/2, video card. I power on the pc, cpu and powersupply fans run, nothing from 3 1/2, hard drive spins, the lights on the keyboard light up when the computer is turned on but then go off and num locks and caps dont come on when pressed.I tried a new video card did nothing, new hard drive nothing, there is 3 ram chips I tried each one individually-still nothing. I tested the voltage on the MB- fine. No beeps from the computer at all when turned on and running. I suspect the cpu is bad, any way to test without swapping.. Anything else I should try…
