Hey guys. My pc had shut down a few days ago and I narrowed down the problem today. Everytime I plug in the 4-pin power socket on the motherboard for the cpu, the pc does not boot at all (no fans running etc). When I unplug the cpu 4-pin on the motherboard, everything is fine. The fans run at their at their normal speed (led and gpu). Obviously, there is no post since the cpu is unplugged. Did my cpu 4-pin power socket short circuit? I tried putting an old cpu in (athlon 3000+) but the same problem occurs. Thanks for any help!

You could have a deficient 4 pin connector or plug. Sounds strange I know but it is possibly during the posting process that it could have inflicted damage. Do you not have a spare PSU that you can use to determine if your system will boot up?

It would be helpful if you could list your system specs.
