So i ran Prime 95 for a bit and i noticed that one core wasn't at 100% load, it would change to various numbers, sometime it would be 0%, 16%, 86% and then back down to 0%.

Prime 95 said that thread has an error and that it detected a hardware failure on that thread. All other cores were running at 100% without issues.

So what could it be?

hardware specs??
Yes user21, you need to go to USER CP in the menu and put your specs in, as for the OP Specs, I would assume they are in the little line under his avatar that says
System Specs

Back on topic...

Yep, could be the cpu, then again could be other stuff. That helped didn't it.:laugh:
What where the temps on the cpu and threads while you were running prime95?

You might wanna try re-seating the CPU and while you got it out check the pins and stuff for foreign stuff, like, corrosion, tarnish, dis-coloring, burnt pins, caps on the MB, and all the usual could be enemys of conductivity.:)

And, if, all looks kosher, then this:
its usually a voltage problem, vcore, set system (BIOS) back to defaults and if it does it again, up vcore a tad.
