I just built a new system and I'm getting very frequent STOP errors. The STOP errors I've hard are 0x00000101 and 0x00000124, which are both Machine Check Exceptions.
I know that I have a hardware error, but I'm not sure if it's the CPU or the motherboard that's the problem. I don't have another CPU of the same socket handy to swap and test.
The reason I suspect the CPU is because in the event log I see a log of these:
A corrected hardware error has occurred. Reported by component: Processor Core Error Source: Corrected Machine Check Error Type: Cache Hierarchy Error Processor ID: 1 The details view of this entry contains further information.
From what I've read, that could be a BIOS issue, but it certainly sounds like a CPU issue.
The motherboard is a GIGABYTE with AMD SB700 southbridge. The CPU is an Athlon X2 7750.
My understanding is that the CPU is a re-branded X4 with two cores disabled, probably because they are faultly.
I want to RMA the faulty part, but I'm not sure which it is. Anyone care to guess?
UPDATE: RESOLVED - After replacing the motherboard, the problem turns out to be "Cool 'n Quiet". Disabling "Cool 'n Quiet" in the BIOS suddenly resolved the issue. No more BSODs.
