How to Fix STOP 0x0000005A Errors

Some of these steps will only work if you're in Safe Mode. Learn how to start Windows in Safe Mode if you're not familiar with doing that.

  1. Restart your computer if you haven't already done so.

    Most 0x0000005A blue screens are one-time issues and won't appear again after restarting. While this may indicate a problem with a Windows service, it may not, and without being told on the BSOD which service is the problem, there's little to be done if things start working again.

  2. Remove any recently installed hardware. If the STOP 0x0000005A error occurred after making hardware changes, it's highly likely that you can fix the error by removing the device.

    If removing the hardware fixes the STOP 0x0000005A error, consult the device's manual or the manufacturer's website for specifics on which computer systems or devices are compatible with it.

  3. Roll back any recently installed drivers. If a recent driver update caused the STOP 0x0000005A error, reverting back to a previous version should fix it.

    If you boot into Safe Mode with network connectivity and you're able to plug the device back in while in Safe Mode, you can take this time to scan for new drivers with a driver updater tool. It's possible that the first driver that caused the error was corrupt or was the wrong driver.

  4. Uninstall any recently installed programs. Some software will install device drivers even if you didn't accompany them with hardware changes, drivers which might have caused the 0x5A error.

  5. Perform a System Restore if you're able to get far enough to do that.

  6. Complete any remaining STOP error troubleshooting steps if none of the above has worked out. While those methods will probably fix the majority of 0x5A BSODs, the ideas in our basic troubleshooting guide should help out the rest of you.
