Another possible cause for WHEA_UNCORRECTABLE_ERROR: Overheating?
- Problem:
- Win8.1. System experiences terrible slow downs.
- Eventually even BSODs with whea_uncorrectable_errors crop up.
- Root Cause:
- Trying to do root cause analysis, I consider:
- Search for “Windows woes after 8.1 upgrade” (online searches lead to results, but seem not applicable here).
- Internet (speed test shows normal):
- Virus: I have Window Essentials, but also try Malwarebytes – prognosis negative.
- GPU (Bitcoin miner?), CPU. GPU-Z shows no problem there :
- CPUID HWMonitor to the rescue: GPU utilization looks good here also, but what is this with the CPU temperatures?!?!
- On opening up the case and examining the CPU: poorly managed cable blocked the fan heat sink.
- Trying to do root cause analysis, I consider:
- Solution: Cable ties! (This new video card install proved more expensive than it should).
- Other thoughts:
- Why did Windows Performance Metering show the apparently throttled CPU still as mostly idle (It still showed single digit percentages for CPU utilization even when computer was positively crawling)?
