2600k doesn't work unless I disable a core, fixable?

[Momo0730]

So recently purchased a used mobo-ram-cpu combo for a build. The seller told me the CPU won't work unless a core is disabled and couldn't tell me for sure why this was the case. I was just wondering if anyone here had any suggestions on possibly fixing this or if I'm stuck with running it at 3 cores. 

 

Cheers!

Is the CPU overclocked?

He had it overclocked, but I've reverted everything to default. And he said the problem was present when he first got the CPU.

Well if the problem was present when he bought the cpu, he would have sent it in for replacement.

I am guessing he went too far with his overclocks and broke something.

Sadly there is nothing you can do.

I figured, i tried everything I could think of but thought I'd ask more knowledgeable people. I'm fine with 3 cores anyways since its only gonna be used as a word processing/browsing PC. Thanks
