Windows NT Kernel (ntoskrnl.exe) (ntoskrnl.exe)
What is this error?
The Windows kernel itself. When this appears as the faulting module, the actual cause is usually a driver or hardware issue that corrupted kernel memory.
Common causes
- RAM corruption
- driver corrupted kernel memory
- hardware failure
- overclocking instability
How to fix it
- This is rarely the actual cause — look deeper at the stack trace
- Run memtest86
- check all driver versions
- reset BIOS overclocks
Too many steps? Crashless can diagnose this automatically — checks your drivers, temps, VRAM, and 400+ known error patterns.

ntoskrnl.exe appearing as the faulting module in a crash dump is misleading — it means the kernel itself crashed, but the ROOT cause is almost always something else that corrupted kernel memory. Think of it like blaming the messenger. The real cause is usually:
- RAM hardware failure or instability (the #1 cause),
- A driver that corrupted kernel memory structures long before the crash occurred,
- CPU overclocking instability causing calculation errors,
- Failing storage device causing corrupted data to be loaded into memory. Diagnosis approach: don't stop at ntoskrnl.exe — look at the full stack trace for any third-party .sys files. Run memtest86 for 8+ hours. Check all hardware with stress tests. If truly no other driver is in the stack, this is likely a hardware problem.
When to seek help
If this error keeps happening after trying the fixes above, it may point to a deeper hardware or system issue. Consider professional help if:
- The crash occurs across multiple games or applications
- You see the same error after a clean Windows install
- Your PC is less than a year old (could be a warranty issue)
- You smell burning or hear unusual sounds from your PC
