How to Fix Code 29 Errors

The code 29 error is one of several Device Manager error codes. It will almost always display in the following way:

This device is disabled because the firmware of the device did not give it the required resources. (Code 29)

What Causes Code 29 Errors?

If you get this error message while trying to use a hardware device, it means the hardware is disabled. In other words, Windows sees that the device exists, but the hardware itself is essentially turned off.

The code 29 error could apply to any hardware device; however, most appear on video cards, sound cards, and other devices that are integrated onto the motherboard. Details on Device Manager error codes are available in the Device Status area in the device's properties.

How to Fix a Code 29 Error

Try these steps in order until the error is resolved.

1. Restart your computer. The error code might be caused by a temporary problem with the hardware that a simple reboot could fix.

2. Use System Restore to undo recent system changes. If you think a change made to important system files is the cause for the error, System Restore can undo it.

3. Update drivers for hardware devices that might be related to the code 29 error. For example, if you see the error when you play a 3D video game, try updating the drivers for your video card.

4. Roll back your drivers. If the code 29 error started appearing after you updated a particular hardware device, rolling back its driver will revert to a version that (hopefully) won't cause the same problem.

5. Reinstall the device drivers. Properly reinstalling a driver is not the same as updating one. A full reinstall involves completely removing the currently installed driver and then letting Windows install it again from scratch.

6. Enable the hardware device in your system BIOS. For example, if the code 29 error is appearing on a sound or audio device, enter BIOS and enable the integrated sound feature on the motherboard.

   Some cards or motherboard features may have physical jumpers or DIP switches that need to be enabled to work properly.

7. Clear the CMOS if you think a BIOS misconfiguration could be the reason that a piece of hardware is disabled or not able to supply resources. This will return the BIOS to their default factory settings.

   If that doesn't work, consider replacing the CMOS battery.

8. Reinstall the hardware by removing all associated drivers and software, then reinstall or reconfigure the device.

9. Reset the expansion card if the device isn't integrated into the motherboard. Improperly seated hardware might be recognized by Windows, but won't work properly.

10. Replace your hardware. If the hardware device is still unresponsive, replace it yourself, or take your PC to a professional computer repair service.

11. Repair Windows to restore all Windows files to their working versions.

12. Perform a clean installation of Windows. Only do this as a last resort, because it will start you with a fresh copy of the operating system (i.e., it will delete everything you have).
