Windows stopped with a SYSTEM_THREAD_EXCEPTION_NOT_HANDLED bug check because a system thread raised an exception that no error handler caught.
Observed message
Bug Check 0x7E: SYSTEM_THREAD_EXCEPTION_NOT_HANDLED
Why it happens
- A system thread raised an exception that the kernel could not handle safely.
- A faulty or incompatible driver triggered the unhandled exception.
- Memory access violations or other low-level faults destabilized the system thread.
How to fix it
- Check crash dump details for the exception address and the driver or module involved.
- Update, roll back, or remove the most likely faulting driver.
- Review recent system changes if the blue screen started after a driver, firmware, or hardware update.
