WHEA 18 Cache Hierarchy Error reboots insanity

vaselineontoast · 2026-07-06T09:29:19-0400

Hello.
Couple weeks ago i was unfortunate to cross path with infamous WHEA Logger Event ID 18 Machine Check Exception Cache Hierarchy Error. Every time when i want to play something demanding like Warframe, total war warhammer 2 or even garrys mod. Screen goes dark after just clicking icons and whole pc just restart itself.

Only thing that is registered its a WHEA bug in a Event viever with random APIC ID (1, 8, 9, 12...). When looking around other forums and this one , noticed a large amount of these bugs. My bet its a windows updates, but sadly i don’t remember when the crashes appeared. Checked temps, played around in bios, checked for mechanical damage, and no fix. Below i put things that i tried and also specs.

Updated everything that needed update (Windows, drivers,Bios)
Memtest86 (passed)
I uninstalled gpu drivers with DDU and installed multiple different with no success
Checked for temperature, between 70 to 80
Re pasted and add new termopads to gpu
Under-clocking, over-clocking didn’t bring any results
Bios reset to default settings didn’t bring any results
Disabled Precision Boost Overdrive (PBO) no success
Disabled Global C-States, nope
Tested each XMP profiles (3000,3200,3600) no success
Added positive voltage offsets and tested each. Added +0.025 V to cpu and worked only for like 3 hours and crashes and started adding more voltages to test them with no results (+0.050, V+0.075, V+0.100 V)
Removed all CPU overclocking with voltages and none voltages, no success

PCspecs:

WHEA

The WHEA bug in the Event Viewer can be caused by various factors, including hardware failures, outdated or corrupted system drivers, or issues with the processor. To troubleshoot this bug, users can follow these steps:

Check Event Viewer: Open Event Viewer and navigate to the Windows Logs section to check for WHEA errors.

1
Update Drivers: Ensure that all system drivers are up to date, as outdated drivers can cause WHEA errors.

2
Run SFC & DISM Scans: Use the System File Checker (SFC) and Deployment Imaging Service and Management Tool (DISM) to repair corrupted system files.

1
Perform an In-Place Upgrade: If the issue persists, consider performing an in-place upgrade of the Windows operating system to fix the problem without deleting files.

1
By following these steps, users can diagnose and potentially resolve the WHEA bug in the Event Viewer. If the problem continues, it may be necessary to seek professional assistance or consult with a hardware or software technician.

Hi. Thanks for answers.

All drivers are up to date

Did the DISM /Online /Cleanup-Image /RestoreHealth and sfc /scannow. With these results: Windows Resource Protection did not find any integrity violations.

Here are detailed info about whea errors from event viever
There are 19 errors. When talking with chagtpt he noticed that they all pretty much the same ( MCABank 5 and 0xbea0000001000108)
