0X0000007E

Blue Screen (BSOD) SYSTEM_THREAD_EXCEPTION_NOT_HANDLED Applies to: Windows 7, Windows 10, Windows 11

What it means

A system thread generated an error a driver didn't catch — very commonly graphics or Wi-Fi drivers right after an update.

Also seen as: SYSTEM_THREAD_EXCEPTION_NOT_HANDLED, 0x7E

Quick fix steps

  1. Boot into Safe Mode and check whether it stops happening.
  2. Update your graphics and Wi-Fi drivers first — the two most common causes.
  3. Roll back any driver updated right before the crashes started.

Frequently Asked Questions

Is this the same as other driver-related stop codes?
It's in the same general family (a driver causing an unhandled system exception), similar in spirit to IRQL and KMODE_EXCEPTION errors, though the exact technical trigger differs.
Does updating Windows itself help with this?
Yes, sometimes — Microsoft periodically ships driver compatibility fixes through regular Windows updates, so keeping Windows current is a reasonable general step alongside updating the specific driver.

Other error codes

0X0000000A — IRQL_NOT_LESS_OR_EQUAL

Almost always a driver issue — most commonly network, audio, or graphics drivers.

0X000000EF — CRITICAL_PROCESS_DIED

A core Windows process crashed unexpectedly — often tied to a recent update or corrupted system files.

0X0000001E — KMODE_EXCEPTION_NOT_HANDLED

A driver running in kernel mode hit an error it couldn't recover from — usually a specific faulty or outdated driver.
