In a computer, system resources include the interrupt request (IRQ) line, direct memory storage (DMA) channel, input/output (I/O) Port, and memory address. When the same system resources are allocated to two or more devices, a hardware conflict will occur and conflicting hardware devices will not work properly. The following methods can help you solve hardware conflicts.
1. Ensure that the device driver is installed only once.
1. Click Start, point to settings, click control panel, and double-click system ".
2. Click the Device Manager tab and find the duplicate device.
3. if a device appears twice but only one of these devices is installed, delete the device that appears each time by right-clicking the duplicate device, click "delete" (1) wyjc1.tif.
4. reinstall the driver of the device.
Ii. View resource settings
Make sure that the device appears only once on the "Device Manager" tab. Check its resource settings. On the "Device Manager" tab of "System Properties", double-click a device that is in conflict, click the "Resources" tab to check whether the device's resource settings are correct (2) wyjc2.tif. If the "Resources" tab is not displayed, the device does not use any resources.
Iii. Are there any hardware conflicts of the "system retained" type?
If the "manual configuration" button is displayed on the "Resources" tab, it indicates that the device is in conflict or has other problems and has been disabled; or The resource settings used by the device work properly, but does not comply with any known configuration. If you see the resource setting box on the "Resources" tab, check whether there is a hardware conflict of the "system retained" type: on the "Device Manager" tab of "System Properties", double-click the conflicted device and view the "Conflicted Device List" on the "Resources" tab ". If no conflict is listed in the list of conflicting devices, the devices being viewed do not have a hardware conflict. In this case, you can restart the computer so that Windows can reconfigure the hardware. Sometimes, even if the resources used by a specific device conflict with the reserved resources of the computer, such conflicts may not occur. If no other problems occur, you can ignore this resource conflict. If a conflict occurs on the device, continue with the following solutions.
4. Configure one or more devices to use different resources
If two devices are configured to use the same resources, you can configure one or both devices to use different resources to solve hardware conflicts.
1. on the "Device Manager" tab of "System Properties", double-click a conflicted device and view the "List of conflicted devices" on the "Resources" tab ", determine which resource settings conflict with other devices.
2. Under the resource settings list of "resource type" and "Settings", double-click the icon next to the settings that conflict with other resources. If you receive a message indicating that the resource setting can be changed only after the "use automatic settings" check box is cleared, click "OK" to clear the "use automatic settings" check box, double-click the icon next to "Settings" again.
3. Scroll through available resource settings and read "conflict information" for various settings ". If you find that a setting does not conflict with another device, keep the selected setting in the "value" box, click "OK", and click "OK" again ", close the "System Properties" dialog box and restart the computer.
You may need to adjust the jumper on the hardware card to conform to the new settings. You may need to run the configuration utility provided by the hardware vendor, depending on the hardware type. If the Jumper settings on the card are incorrect, the hardware will still not work after the conflict is resolved.
5. Release reserved resource settings
If "conflict information" shows that all settings conflict with other devices, click "cancel" consecutively to close the "System Properties" dialog box and release the reserved resource settings:
1. on the "Device Manager" tab of "System Properties", double-click "computer ".
2. Click the "retain resources" tab and click the resource type in conflict (3) wyjc3.tif. If a resource setting has been retained, no device in the system can use it. The settings box lists the reserved resource settings. If this box is blank, the settings of this type are not retained.
3. Click the specific resource under "Settings", click "delete", and then click "OK ".
6. Disable devices that are no longer needed
If one of the conflicting devices is no longer needed, disable the devices to solve the hardware conflict. If you disable plug-and-play devices, other devices can automatically obtain the resources of these devices. If the disabled device is not an out-of-the-box device, you must delete it from the device management hardware list and then remove it from the computer to release the occupied resources. Therefore, before disabling a device that is no longer needed, determine whether the device can be "out-of-the-box ".
(1) determine the device "plug-and-play ":
1. on the "Device Manager" tab of "System Properties", double-click the device to disable.
2. on the "Resources" tab, find the "manually set configuration" button. If this button appears, it indicates that the device can be "out-of-the-box ".
3. Click OK to return to the Device Manager tab.
(2) disable the "out-of-the-box" device:
1. on the "Device Manager" tab, double-click the device.
2. Under "device usage", click to select the "Disable in this hardware configuration file" check box (4) wyjc4.tif, click "OK", and then click "OK" again ".
3. If you are prompted to restart your computer, restart it. If you are not prompted to restart the computer, click OK to close the System Properties dialog box and restart the computer.
(3) Disable out-of-the-box devices:
1. on the "Device Manager" tab, click the device you want to disable, and then click "delete ".
2. Click OK ".
3. restart the computer.
After the above six steps, I believe that the hardware conflict in your computer system has been solved!
