Prime95, Have I Got Two Bad Core CPUs??

[Gelbs]

Call me paranoid, lol. But I've been doing some tests with my new computer, to check for errors etc. And I heard about Prime95. I've been doing some checks with it, and I am worried I have 2 bad Cores/CPUs. I have an 8 core processor, but according to Prime95, CPU 2 & 3 have errors. Baring in mind I have absolutely no idea about it, though! This is what it says (for both cores)...

Are you experiencing any problems running games or applications?

Now it sometimes seems fine when doing tests :/ really is some confusing ****! Lol.

I've done tests with Memtest, Furmark etc, and all seems fine. But, this all stems when I play FIFA. It's the only game that has restarted my computer, and freezes with a buzzing/ringing sound coming from the speakers. I played Far Cry 4 for well over an hour (let it run) and my GPU got to over 80 degrees like with the 3d tests etc, and it was fine. It could just be FIFA, but it's still making me concerned. Not sure what to think.
