MACHINE_CHECK_EXCEPTION

What it means

The CPU reported a hardware error. On newer systems the same thing shows as WHEA_UNCORRECTABLE_ERROR.

Common causes

• Overclock or undervolt
• Overheating
• Unstable power

How to fix it

1. Undo any overclock or undervolt, including XMP/EXPO memory profiles, and test at stock settings for a day.
2. Check CPU temperatures under load with HWiNFO.
3. Make sure all power cables to the board (24-pin and CPU 8-pin) are firmly seated.
4. Test the RAM: run Windows Memory Diagnostic (search mdsched) or MemTest86 from a USB stick. Any error means a stick or its speed setting is the problem.
