 * Fix IRQ Faults to Cure Hardware Problems**

The PCI hardware specification was supposed to fix the problem of IRQ conflicts, by allowing devices to safely share IRQs. However, even with an advanced Windows 7 system, you may still find that some hardware devices do not function properly when sharing a particular IRQ. For example, IRQ conflicts can affect sound cards, which may produce an audible buzzing noise through the speakers when using one IRQ, but not when using another.

To cure the error, you should contact the device’s manufacturer to obtain an updated driver. If one doesn’t exist, you can try assigning the device to a different IRQ manually as follows:-


 * 1) Click **Start** > **Control Panel** > **Device Manager**.
 * 2) Expand the category for the device that is having a problem, then double-click on the device name.
 * 3) Check the Device status box to see if any conflict is reported.
 * 4) Click on the **Resources** tab. If there are any conflicting devices they should be shown in the Conflicting devices list, but depending on the fault this may not be the case even if there is an IRQ conflict.
 * 5) Un-tick/check the option **Use automatic settings**.
 * 6) Select **IRQ** in the resources list and click **Change Setting**.
 * 7) Use the up and down arrow buttons to change the IRQ value. If the IRQ change will cause a conflict, it will be shown in the text box at the bottom of the screen.
 * 8) Click **OK** > **OK** and close Device Manager to apply the change
