What does 0x0000007E mean?
It means a system thread generated an exception that the error handler did not catch. Most commonly caused by a bad GPU driver or corrupted system file.

A driver or system file loads during boot and immediately crashes. Safe Mode bypasses most third-party drivers, allowing you to update or remove the problem driver.
Is this a hardware failure?
Not necessarily. In most cases it is a driver issue. If updating all drivers and running SFC/DISM does not fix it, test your RAM with MemTest86 and check drive health.
Can I fix this without reinstalling Windows?
Yes. Safe Mode driver updates and SFC/DISM repair fix the majority of 0x0000007E cases without reinstalling.
When should I call a professional?
If Safe Mode itself crashes, or if the error persists after driver updates, SFC, DISM, and BIOS update, the issue may be failing hardware that requires in-person diagnosis.
