SOLVED! “The Bugcheck Was: 0x0000007e”

Blue Screen of Death (BSOD) is one of the last things that Windows users want to see while using their computers. Whenever people run into BSOD, it means that things have gone seriously wrong and the system must restart. Usually, by taking a look at the entries in Event Viewer, Windows users could get a general idea about the cause of BSOD. Check out this article if you see an entry that says “The computer has rebooted from a bugcheck. The bugcheck was: 0x0000007e” in Event Viewer.

The Usual Suspects

Generally speaking, 0x0000007e is one common bugcheck code for BSOD and it indicates a SYSTEM_THREAD_EXCEPTION_NOT_HANDLED error. That means the operating system thread generated an exception that the error handler did not catch. Once it comes to 0x0000007e, you should take the possibilities down below into account.

  • Hardware: All in all, if you use components that Windows won’t support, BSOD is one of the consequences. That is why it’s a good idea to stick to hardware listed in the Microsoft Windows Marketplace Tested Products List.
  • Device drivers/system service: If either device drivers or system service of your PC act up in the course of operation, you may come across BSOD.

“The Bugcheck Was: 0x0000007e”: Solutions

Note: If BSOD is giving you a hard time as you get to the bottom of the situation, you should boot into Safe Mode.

In the beginning, you should try out basic troubleshooting techniques down below:

  • If a driver is mentioned in the bugcheck entry, you should get rid of that driver at the earliest opportunity. For good measure, disable/uninstall suspicious drivers or services recently added to your PC as well.
  • Read the System Log in Event Viewer for other error messages. By doing so, you narrow down the device or driver that causes bug check 0x0000007E.
  • If possible, proceed to disable memory caching of BIOS and see how things turn out.
  • Run hardware diagnostics, especially the memory scanner, then assess the result.

Think About Disk Space

Generally speaking, if disk space on the boot partition is inadequate, Windows would run into problems. In the case of the 0x0000007e error, the lack of space should ensure that BSOD will greet you as soon as you boot up Windows. To return things to normal, free up space by deleting  junk files, Internet cache files, application backup files, etc. That is going to help improve the stability of Windows.

If the current drive is too small, you may want to consider installing Windows to another drive entirely.

Update Drivers

The root cause of many errors including 0x0000007e is the obsolescence of drivers. Hence, every time you see the ”The bugcheck was: 0x0000007e” entry in Event Viewer, update your drivers. In the case that you could tell which driver is the one behind the error, dedicate your attention to it.

Third-Party Driver Managers 

Nowadays, a number of apps would let you keep all your drivers up-to-date with relative ease. Examples include Driver Booster, Driver Easy, Snappy Driver Installer, etc. Download and install the driver manager that you like then let it handle the updates of drivers.

Manual Update

If you don’t like using apps for driver updates, feel free to update the drivers manually by going through theese teps.

  • Step 1: Go to Search bar, type device manager and press Enter.
  • Step 2: Locate the devices with outdated drivers, right-click each of them and pick Update driver.
  • Step 3: Follow the instructions to update the drivers.

Chang Video Adapter

On occasions, display adapters may be behind the appearance of the “The bugcheck was: 0x0000007e” entry in Event Viewer. If you’re using multiple display adapters, swapping between them and determine if the error persists.
