Microsoft suggests the following possible causes: * lack of disk space * incompatible BIOS settings or outdated BIOS * incompatible/ damaged video drivers or system service * third-party remote control programs

When the cause of 0x0000007E error is not obvious, we recommend to make your computer configuration as simple as possible, use as little devices as you can and remove or disable third-party drivers before you start troubleshooting. If the error disappears, start adding new devices and install drivers one by one until the error occurs again (if at all). This method helps detect the source of the 0x0000007E error and works with other Windows BSOD errors.

  • Make sure you have enough disk space. Start up in Safe mode and delete old/ unnecessary/ temporary files

if the space is insufficient. Alternatively, you can use an operating system on another hard drive with sufficient disk space to access the files on your current hard drive. * You might need to update BIOS (contact your vendor for the update) to resolve 0x0000007E. * Often, 0x0000007E error message includes Win32k.sys that indicates a conflict with a third-party remote control program. Use Recovery Console to delete the problematic service file.

  • Incompatible drivers are another possible cause of 0x0000007E. If the error message includes a driver’s name or another file’s name, disable it, update or remove if updating doesn’t help. (The example above points to WUSB54GCx86.sys, a driver for wireless USB adapter). Remove newly installed drivers. If 0x0000007E problem remains after driver update, remove all drivers not digitally signed by Microsoft and all third-party drivers (remover them form %Windir%\System32\Drivers to another folder. You can do so by accessing your hard disk from Windows installation on another hard drive or Recovery Console.) Attention! Don’t remove IDE or SCSI controller drivers, or files with 13/8/2001 creation date!
