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.
To check IRQ usage:
1 Click Start, then select Control Panel, then Performance and
Maintenance
.
2 Click System, click the Hardware tab, then click Device Manager. The
Device Manager opens.
3 Click View, select Resources by type, then double-click Interrupt request
(IRQ)
. All IRQs and their hardware assignments are displayed.
To free IRQ resources for the new device:
1 In the Device Manager, 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 select Disable.
The device or port is disabled.
