This article covers error codes that are generated by Device Manager in Windows. You probably reached this article because Device Manager or another tool like DXDiag reported an error code, and you are not sure how to resolve it. In this article, we will help you find your error code and suggest what you might try to correct the error.
If the above steps didn't help you resolve your problem or were not available, locate your error code in the following table, and follow the recommended resolutions for that error code. You may also click the specific error code to get more detail information.
Note This article doesn't contain all error codes generated by Device Manager. If you are getting an error code that isn't listed here, you can contact the hardware device vendor's technical support or Microsoft Support for help.
Right-click the device that has the problem, and then click Properties. This opens the device's Properties dialog box. You can see the error code in the Device status area of this dialog box.
In the device's Properties dialog box, click the Driver tab, and then click Update Driver to start the Hardware Update Wizard. Follow the instructions to update the driver. If updating the driver does not work, see your hardware documentation for more information.
Note You may be prompted to provide the path of the driver. Windows may have the driver built-in, or may still have the driver files installed from the last time that you set up the device. If you are asked for the driver and you do not have it, you can try to download the latest driver from the hardware vendor's website.
Note You may be prompted to provide the path of the driver. Windows may have the driver built-in, or may still have the driver files installed from the last time that you set up the device. However, sometimes, it will open the New Hardware Wizard which may ask for the driver. If you are asked for the driver and you do not have it, you can try to download the latest driver from the hardware vendor's website.
This error can occur if two devices that are installed on your computer have been assigned the same I/O ports, the same interrupt, or the same Direct Memory Access channel (either by the BIOS, the operating system, or both). This error message can also appear if the BIOS did not allocate enough resources to the device.
Use Device Manager to determine the source of and to resolve the conflict. For more information about how to resolve device conflicts, see the Help information about how to use Device Manager. This error message can also appear if the BIOS did not allocate sufficient resources to a device. For example, this message will display if the BIOS does not allocate an interrupt to a USB controller because of an invalid multiprocessor specification (MPS) table.
This error message can also appear if the BIOS did notallocate sufficient resources to a device. For example, this message will be displayed if the BIOS does not allocate an interrupt to a USB controller because of an invalid multiprocessor specification (MPS) table.
The following steps might only work if the device is a Plug and Play device. If the device is not Plug and Play, you can refer to the device documentation or contact the device manufacturer for more information.
To roll a system back to the most recent successful configuration of the registry, you can restart the computer in Safe Mode and select the Last Known Good Configuration option, or if you've created a system restore point, you can try restoring to it.
This error means that Windows is in the process of removing the device. However, the device has not yet been completely removed. This error code is temporary, and exists only during the attempts to query and then remove a device.
The device is installed incorrectly. The problem could be a hardware failure, or a new driver might be needed. Devices stay in this state if they have been prepared for removal. After you remove the device, this error disappears.
The device requires manual configuration. See the hardware documentation or contact the hardware vendor for instructions on manually configuring the device. After you configure the device itself, you can use the Resources tab in Device Manager to configure the resource settings in Windows.
Your computer's system firmware does not include enough information to properly configure and use this device. To use this device, contact your computer manufacturer to obtain a firmware or BIOS update. (Code 35)
This device is requesting a PCI interrupt but is configured for an ISA interrupt (or vice versa). Please use the computer's system setup program to reconfigure the interrupt for this device. (Code 36)
For more information about how to change BIOS settings, see the hardware documentation or contact the manufacturer of your computer. You can also try to use the BIOS setup tool to change the settings for IRQ reservations (if such options exist). The BIOS might have options to reserve certain IRQs for peripheral component interconnect (PCI) or ISA devices.
A duplicate device was detected. This error occurs when a bus driver incorrectly creates two identically named sub-processes (known as a bus driver error), or when a device with a serial number is discovered in a new location before it is removed from the old location.
No resolution is necessary. This error code is only used to indicate the disconnected status of the device and does not require you to resolve it. The error code resolves automatically when you connect the associated device to the computer.
Windows cannot gain access to this hardware device because the operating system is in the processof shutting down. The hardware device should work correctly next time you start your computer. (Code 46)
No resolution is necessary. The hardware device should work correctly next time that you start the computer. This error code is only set when Driver Verifier is enabled and all applications have already been shut down.
Windows cannot use this hardware device because it has been prepared for safe removal, but it has not been removed from the computer. To fix this problem, unplug this device from your computer and then plug it in again. (Code 47)
The system hive has exceeded its maximum size and new devices cannot work until the size is reduced. The system hive is a permanent part of the registry associated with a set of files that contains information related to the configuration of the computer on which the operating system is installed. Configured items include applications, user preferences, devices, and so on. The problem might be specific devices that are no longer attached to the computer but are still listed in the system hive.
Windows cannot apply all of the properties for this device. Device properties may include information that describes the device's capabilities and settings (such as security settings for example). To fix this problem, you can try reinstalling this device. However,we recommend that you contact the hardware manufacturer for a new driver. (Code50)
There is currently no resolution to this problem. To help diagnose the problem, examine other failed devices in the device tree that this device might depend on. If you can determine why another related device did not start, you might be able to resolve this issue.
Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)
This is an intermittent problem code assigned while an ACPI reset method is being executed. If the device never restarts due to a failure, it will be stuck in this state and the system should be rebooted.
Hello! My problem is with the drivers nvidia video cards, the fact is that after updating drivers nvidia video cards, it stops working and error "code 43". Latest audited version 344.75 drivers I work with, and subsequent versions of the drivers have refused to work.No matter what it is the operating system! I hope you can help me with this problem!
This extremely generic message could mean there's a true hardware issue or it could simply mean that there's a driver problem that Windows isn't seeing as such but that the hardware is being affected by.
1. Restart your computer if you haven't done so already.
There is always the chance that the error Code 43 you're seeing on a device was caused by some temporary problem with the hardware. If so, a restart of your computer might fix the Code 43 error.
Note: Some users have also reported that powering off their computer completely (not just a reset) and then turning it back on has corrected their Code 43 issue, especially if it exists on a USB device. In the case of a laptop, turn it off and remove the battery, wait a few minutes, and then put the battery back in and start the computer.
2. Did you install a device or make a change in Device Manager just before the Code 43 error appeared? If so, it's possible that the change you made caused the Code 43 error.
Undo the change if you can, restart your PC, and then check again for the Code 43 error.
Depending on the changes you made, some solutions might include:
3. Reinstall the drivers for the device. Uninstalling and then reinstalling the drivers for the device is a possible solution to a Code 43 error.
Important: If a USB device is generating the Code 43 error, uninstall every device under the Universal Serial Bus controllers hardware category in Device Manager as part of the driver reinstall. This includes any USB Mass Storage Device, USB Host Controller, and USB Root Hub.
Note: Properly reinstalling a driver, as in the instructions linked above, is not the same as simply updating a driver. A full driver reinstall involves completely removing the currently installed driver and then letting Windows install it over again from scratch.
