Operating system hardware conflict resolution six technical _WINDOWSXP

On a computer, system resources include interrupt request (IRQ) lines, Direct memory storage (DMA) channels, input/output (I/O) ports, and memory addresses. A hardware conflict occurs when the same system resource is assigned to two or more devices, and the conflicting hardware devices will not function properly. The following methods can help you resolve hardware conflicts.

　　 first, make sure that the device driver is installed only once

1. Click Start, point to Settings, click Control Panel, and then double-click System.

2. Click the Device Manager tab, and then locate the duplicate device.

3. If a device appears two times and only one such device is actually installed, remove each occurrence of the device by right-clicking the device that appears repeatedly, and then clicking Delete (Figure 1) wyjc1.tif.

　　

4. Reinstall the device driver.

　　Second, view resource settings

Make sure the device is on the Device Manager tab, after only one occurrence, check its resource settings: On the Device Manager tab of System Properties, double-click the conflicting device, and then click the Resources tab to verify that the resource settings for the correct device (see Figure 2) are wyjc2.tif. If the Resources tab does not appear, it indicates that the device is not using any resources.

　　 Third, is there a "system retention" type of hardware conflict?

If the Resources tab displays the manually Set Configuration button, the device has a conflict or other problem, is disabled, or the resource settings used by the device work correctly, but do not conform to any known configuration. If on the Resources tab, see the Resource Settings box, determine if there is a system retention type of hardware conflict: On the Device Manager tab of System Properties, double-click the conflicting device, and then on the Resources tab, view the Conflicting devices list. If no conflicts are listed under the Conflicting Devices list, there is no hardware conflict for the device you are viewing. At this point, you can restart the computer so that Windows can reconfigure the hardware. Sometimes, even if the resources used by a particular device conflict with the reserved resources of the computer, this conflict is likely to be a problem. If there are no other problems, you can ignore this resource conflict. If the conflict causes the device to use problems, continue with the following workaround.

　　 configuration of one or more equipment to make use of different resources

If both devices are configured to use the same resources, one or both of these devices can be configured to use different resources to resolve the hardware conflict problem.

1. On the Device Manager tab of System Properties, double-click the conflicting device, and then on the Resources tab, review the Conflicting devices list to determine which resource settings conflict with other devices.

2. Under the Resource Settings list for resource types and settings, double-click the icon next to the settings that conflict with other resources. If you receive a message stating that you can change resource settings only after you clear the Use Automatic settings check box, click OK, clear the Use Automatic settings check box, and then double-click the icon next to Settings.

3. Scroll through the available resource settings and read "Conflict information" for various settings. If you find that a setting does not conflict with one of the other devices, leave the settings selected in the Value box, click OK, click OK again, close the System Properties dialog box, and restart the computer.

You may need to adjust the jumpers on your hardware card to fit the new settings, and you may need to run the configuration utility provided by your hardware vendor, depending on the type of hardware. If the jumper settings on the card are not correct, the hardware does not work properly after resolving the conflict problem.

　　 release reserved resource settings

If conflict information shows that all settings conflict with other devices, click Cancel continuously, close the System Properties dialog box, and then release the reserved resource settings:

1. On the Device Manager tab of System Properties, double-click Computer.

2. Click the Reserve Resources tab, click the resource type that conflicts (Figure 3) Wyjc3.tif, and if a resource setting is reserved, then no device on the system can use it. The Settings box lists the reserved resource settings. If this box is empty, the settings for that type are not currently reserved.

3. Click a specific resource under settings, click Delete, and then click OK.

　　Vi. Disabling devices that are no longer needed

If one of the conflicting devices is no longer needed, you can disable it to resolve the hardware conflict issue. If you disable a Plug and Play device, other devices can automatically obtain resources for those devices. If a disabled device is not Plug and play, you must remove the device from the hardware list in device management, and then remove it from the computer to free up the resources it occupies. Therefore, before disabling a device that you no longer need, determine whether the device is Plug and play.

(i) Determine the device "Plug and Play":

1. On the Device Manager tab of System Properties, double-click the device you want to disable.

2. On the Resources tab, look for the "Manually Set Configuration" button. If this button appears, the device is capable of "Plug and play."

3. Click OK to return to the Device Manager tab.
(ii) Disabling "Plug and Play" Devices:

1. On the Device Manager tab, double-click the device.

2. Under Device Usage, click to select the Disable in this Hardware profile check box (Figure 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 your computer, click OK, close the System Properties dialog box, and then restart your computer.

　　(iii) Disable non-Plug and Play devices:

1. On the Device Manager tab, click the device that you want to disable, and then click Delete.

2. Click OK.

3. Restart the computer.

After six steps, I believe that your computer system hardware conflict has been resolved!
