|This is a long distance problem with a friend's PC but I'll give as much info as I have.|
It's an HP (no model number) that's running a 295w power supply, Athlon II x4, and 1 SATA Hard Drive. 2 x2GB of DDR3 Ram. No expansion cards and video is indiscreet.
The problem started all of a sudden. When he powers on the PC the monitor receives no signal at all and the PC doesn't post. What happens internally is, when powered on, the case fan and cpu fan spin up for 4 seconds and then stop spinning but the power stays on until it is turned off manually. The power supply has a green LED on the back showing it's good. The motherboard does not have any LEDs.
I had him try a known working monitor and power supply for the heck of it but the problem persists. No changes have been made to the system before or after the problem started. The main ATX connector is fully seated as well as the additional ATX/EPS 12v cable for the CPU.
At this point I would assume it's the CPU, although I find it unlikely that it just died. But with PC components anything can happen.
I would like some feedback to determine if my diagnosis is correct. Thanks.
