Device installation
You have computer problems after adding a new device
Sometimes a new device, such as a PC Card, can cause a system resource (IRQ)
conflict. Check IRQ usage to determine if there is an IRQ conflict.
Checking IRQ usage
To check IRQ usage:
1 Click Start, then click Control Panel. The Control Panel window opens.
If your Control Panel is in Category View, click
Performance and
Maintenance
.
2 Click/Double-click System, click the Hardware tab, then click Device
Manager
. The Device Manager window opens.
3 Click View, then click Resources by type. Double-click Interrupt request
(IRQ)
. All IRQs and their hardware assignments are displayed.
Freeing IRQ resources
To free IRQ resources for the new device:
1 In the Device Manager window, check the device list for a resource
conflict. A resource conflict appears as a black exclamation point in
a yellow circle.
2 Remove the device you are trying to install, then determine which
one of the existing devices or ports you can disable.
3 Right-click the device or port you want to disable, then click Disable.
The device or port is disabled.
