WHEA_UNCORRECTABLE_ERROR
The hardware itself reported an error it could not fix: processor, memory, power or overheating.
How to fix it
- Turn off all overclocking, including XMP and "auto overclock", in the BIOS.
- Check temperatures with a tool like HWMonitor and clean dust from fans.
- Update the BIOS from the PC or motherboard maker.
- Test RAM with MemTest86.
Is it serious?
A hardware warning. If it happens with no overclock and normal temperatures, a part is failing.
