If you're receiving the Code 51 - This Device Is Currently Waiting on Another Device or Set of Devices to Start error, here's how you can fix it.

Code 51 is one of those errors Microsoft fails to explain properly, and they're pretty vague about it. There are only three things we can try.

1: Reboot

We hate to be this lazy, but really, a reboot might help.

2: Remove and Reinstall the Device

Press the Windows Key + S and begin typing in device manager and click on device manager. Windows 7 users can go to Start, Control Panel as well. Find the hardware that's giving you trouble. For this example, we'll use Realtek High Definition Audio. Right-click and select Uninstall.



You will receive a warning that says You are about to uninstall this device from your system. Also, check the box that says Delete the driver software for this device.



Reboot after Windows is finished. Windows will not redetect and reinstall the device you removed. You might want to update your drivers now with Driver Booster.

3: Update Your Drivers

Updating your device drivers should do the trick enabling the Service again. We'd try Driver Booster, reboot, and see if your problem is solved.

If you have a different Device Manager error code, here are all the device manager error codes and solutions.
