I have been experiencing unexpected crashes once or twice a week since building my system a few months ago. The crashes can occur during gaming or simply watching a youtube video.
Event viewer has this error associated with the crashes:
A fatal hardware error has occurred.
Reported by component: Processor Core
Error Source: Machine Check Exception
Error Type: Cache Hierarchy Error
Processor APIC ID: 4
The details view of this entry contains further information.
Event ID: 18
I was wondering if there's an easy fix for this or if this is a defective cpu. Any help would be appreciated, thanks!
This looks like the very common WHEA reboot issue. Symptoms are WHEA errors in Windows event logger, and reboots with a black screen (no bluescreen) at idle or near-idle. Try a beta BIOS with AGESA 184.108.40.206, there are some indications this helps. I'm up to 2 days stable now with it.
