Is my CPU busted?

[Jacob Vile]

So my computer died after a whole year without incident. I've figured out that when the CPU is connected to the PSU, the whole PC won't turn on. Is this a problem with the CPU or the motherboard?

I have an AMD fx8350 processor and a relatively cheap $40 AMD motherboard. PSU is an 860W corsair (a little overkill for my rig), and the graphics card is a gtx 970.

Again, when the CPU is NOT connected, my PC turns on. Leaving everything else connected poses no problem (the 24-pin PSU thing is still connected to the motherboard if that helps at all).

Help is appreciated, thanks!

I have already replaced the PSU, and the problem still occurs.

CPU=Processor.
You meant to say the whole system by CPU?
Or,the CPU connector is connected to motherboard PC won't turn on,something like this?

One of two says you can test this. If you have a spare motherboard, plug the CPU into that. If you have a spare CPU of that chipset, plug it into your motherboard.
I can't really suggest any other way and I know that's not ideal.
One thing I have just thought of - have you tried another PSU? It might be that the CPU power cable (8pin or 4 pin) is busted...

This may indicate the PSU doesn't supply enough current to power the CPU... try a different PSU. You may want to first check the AC power cord is fitted snugh on the PSU, as well as both CPU 4/8 pin and the motherboard 24 pin connectors are fitted all the way in the motherboard. Lose connections can cause power related issues.

By CPU connected, I presume it's about 4/8 pin power connection on MB ???
