Hi people, my cpu has been acting wierd, my pc freezes randomly and the only way to trigger it, is by running prime or other stress test for the cpu, it runs for about 10 seconds then freezes, happens aswell with memtest 86, but only if i test the ram using the 4th core of the processor, once it works that core, the pc freezes, any help here? or i need to RMA my cpu? i5-3570K
