STOP 0x0000013A
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
- A buggy driver — GPU drivers appear disproportionately often for this code
- Faulty RAM or unstable memory overclock
- Low-level utilities (virtual drives, tuning tools) with kernel components
How to fix it
1. Clean-install the GPU driver and update the identified driver moderate
- Clean-install the newest GPU driver (DDU in Safe Mode, then fresh install).
- Update any driver named in the report from the vendor's site.
2. Test RAM moderate
- Run Windows Memory Diagnostic or MemTest86 (4+ passes).
- Disable XMP/EXPO temporarily and compare.
The four parameters on the blue screen
Windows shows four hex numbers with this stop code. Here's what each means — our analyzer decodes them automatically from your dump file.
| Parameter 1 | Type of heap corruption |
| Parameter 2 | Address of the heap |
| Parameter 3 | Address of the corruption |
| Parameter 4 | Reserved |
