Device Manager is a special tool in Windows that allows managing drivers and parameters for the installed hardware. It shows detailed information about each installed device.
Advertisеment
Device manager can show hidden devices. This is helpful when you are testing the installation of a new PnP device. Device Manager provides detailed information in the Properties dialog for each device. Right-click the name of the device, and then click Properties. The General, Driver, Details, and Events tabs contain information that can be useful when you debug errors.
You can find an error code for a device in Device Manager by opening its properties dialog.
If your device is required to start the computer, a problem with your device installation can prevent the computer from starting. In these cases, you have to use the kernel debugger to troubleshoot your device installation.
If your device is not required to start the computer, Device Manager places a yellow exclamation point next that device's name in the Device Manager dialog. Device Manager also provides an error message describing the problem.
Here are error codes that are generated by Device Manager in Windows along with solutions you can apply to resolve the appropriate issue.
Device Manager Error Codes in Windows
Code 1: This device is not configured correctly. (Code 1) | |
| Cause The device has no drivers installed on your computer, or the drivers are configured incorrectly.Recommended ResolutionUpdate the DriverIn 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. | |
Code 3: The driver for this device might be corrupted, or your system may be running low on memory or other resources. (Code 3) | |
| Cause The device driver may be corrupted, or you are running out of memory; the system is running low on system memory and may need to free up or add more memory.Recommended ResolutionsClose some open applicationsIf the computer has insufficient memory to run the device, you can close some applications to make memory available. You can also check memory and system resources, and the virtual memory settings.
Uninstall and reinstall the driver The device driver may have become corrupted. Uninstall the driver from Device Manager and scan for new hardware to install the driver again.
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. Install additional RAM You may have to install additional random access memory (RAM) | |
Code 9: Windows cannot identify this hardware because it does not have a valid hardware identification number. For assistance, contact the hardware manufacturer. (Code 9) | |
| Cause Invalid device IDs for your hardware have been detected by your PC. Recommended Resolutions Contact the hardware vendor. The hardware or the driver is defective. | |
Code 10: This device cannot start. Try upgrading the device drivers for this device. (Code 10) | |
| Cause Typically, the device's hardware key contains a "FailReasonString" value, and the value string is displays an error message defined by the hardware manufacturer. If the hardware key does not contain a “FailReasonString” value the message above is displayed. Recommended resolutions Update the driver 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. Note You may be prompted to provide the path of 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. | |
Code 12: This device cannot find enough free resources that it can use. If you want to use this device, you will need to disable one of the other devices on this system. (Code 12) | |
| Cause 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. Recommended Resolution Windows Vista and later versions of Windows 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. Windows Server 2003, Windows XP, and Windows 2000
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. | |
Code 14: This device cannot work properly until you restart your computer. To restart your computer now, click Restart Computer. (Code 14) | |
| Recommended Resolution Restart your computer. From Start, click Shut Down, and then select Restart. | |
Code 16: Windows cannot identify all the resources this device uses. To specify additional resources for this device, click the Resources tab and fill in the missing settings. Check your hardware documentation to find out what settings to use. (Code 16) | |
| Cause The device is only partly configured and might need additional manual configuration of the resources the device requires.
