KERNEL_MODE_HEAP_CORRUPTION

Windows detected that a kernel memory heap was corrupted. Like other corruption codes, this means a driver wrote where it shouldn't — or the RAM underneath is flipping bits.

Likely causes, most common first

How to fix it

1. Clean-install the GPU driver and update the identified driver moderate

  1. Clean-install the newest GPU driver (DDU in Safe Mode, then fresh install).
  2. Update any driver named in the report from the vendor's site.

2. Test RAM moderate

  1. Run Windows Memory Diagnostic or MemTest86 (4+ passes).
  2. Disable XMP/EXPO temporarily and compare.
