How to Fix the ERROR_PNP_IRQ_TRANSLATION_FAILED

The ERROR_PNP_IRQ_TRANSLATION_FAILED (error code 0x2AD) occurs in Windows when the Plug and Play (PnP) subsystem cannot map or translate an interrupt request (IRQ) to a device during configuration. This failure prevents the device from being correctly initialized or operated, resulting in hardware malfunction or inability to use the device.

Usually, this bug check is caused by resource conflicts, driver issues, BIOS/UEFI misconfiguration, or faulty hardware. also, if you’re running an older version of Windows, it might not handle IRQ translations properly.

How can I fix ERROR_PNP_IRQ_TRANSLATION_FAILED?

1. Update the device drivers

1. Open Device Manager by pressing Windows + X and selecting it.
2. Locate the device with the error (yellow warning icon).
3. Right-click and select Update driver.
4. Choose Search automatically for drivers.
5. If no update is found, download the latest driver from the manufacturer’s website and install it manually.
6. You may also try selecting Uninstall device in step 3 and force the system to reinstall the driver for it after a restart.

If you installed any new hardware lately, start with its driver first. If you want to deal with this problem a lot faster and easier, you should think about using a driver updater tool that will do all that automatically.

2. Resolve hardware conflicts (for advanced users)

1. Open Device Manager by pressing Windows + X and selecting it.
2. Look at the device driver you installed recently, right-click on it and select Properties.
3. Navigate to the Resources tab to check for conflicts.
4. If conflicts are identified, reassign the IRQ or address by manually changing resource settings (requires advanced knowledge).

3. Update BIOS/UEFI Firmware

Although less likely, the ERROR_PNP_IRQ_TRANSLATION_FAILED may be caused by a wrong BIOS interrupt handling caused by an outdated firmware. In this case, we recommend updating your BIOS.

We have a complete guide on how to update the BIOS. For advanced users, it’s also possible to configure hardware interrupts from BIOS/UEFI to avoid such conflicts.

4. Use the Hardware and Devices troubleshooter

1. Press Windows + R, type msdt.exe -id DeviceDiagnostic and press Enter.
2. This will open the Hardware and Devices troubleshooter.
3. Click Next to start the process and follow the on-screen instructions to go through and fix the problem.

The Hardware and Devices tool will soon be retired by Microsoft, but for now, it’s an excellent tool to identify and fix hardware conflicts.

Additional potential solutions to fix this error

• If the error appeared after you installed a new hardware device, swap out the device or test it on another system to determine if it is defective.
• Also, check the physical connections to ensure there are no loose cables or damaged pins.
• Check for any OS updates by navigating to Settings > Update & Security > Windows Update.
