Method 3: Unplugging external drives and other peripherals

As some users have pointed out, the issue can also be caused by an external device connected through USB. To pinpoint the culprit, every external drive and non-necessary peripheral (mouse, keyboard) and reboot to see if the error returns.

If your computer starts up just fine, systematically connect the rest of peripherals until you pinpoint the cause of the error. Once the culprit is identified, uninstall the driver belonging to that peripheral via Device Manager in order to force Windows to reinstall it. Here’s a quick guide on doing this:

  1. Press Windows key + R to open up a Run box. Then, type “devmgmt.msc” and press Enter to open up Device Manager.
  2. Inside Device Manager, right-click on the device that you previously identify and choose Uninstall Device.
  3. Once the device has been uninstalled, reboot your computer to see force Windows to uninstall the driver and see if the issue returns.

If the error is still occurring at every startup, move down to the next method below.

Method 4: Performing a repair install

In the event that some party interference (malware or otherwise) has damaged POST files, you might need to reinitiate some Windows components in order to resolve the issue.

You can always go of a clean install, but a more elegant solution would be to perform a repair install. This procedure will reinitiate all Windows files while allowing you to keep all your personal files and applications.

Once the procedure is complete, see whether you’re still seeing the “Error sending End Of Post message to ME” error during startup. If you are, move over to the final method

Method 5: Investigate your hardware for failure

If you’re still struggling with the “Error sending End Of Post message to ME” error even after you performed a repair install (or clean install), there’s a high chance that the issue is caused by hardware failure.
