Switching IRQs

A second check reveals that the Digital camera is connected via usb, not the serial port. So, the USB is conflicting with the ATI Rage Pro video card. So what I need to do is change the IRQ of one of the 2 devices. THANKS.

First, check for, and install any updated drivers for your motherboard / chipset. These often include improved IRQ steering over the default windows drivers.

If that doesn't take care of things:
Open up device manager.
Remove any devices that you do not use (COMM Ports)
Expand the system devices branch.
Select PCI Bus.
In the properties box, click on the IRQ steering tab.
Disable IRQ steering.

Apply and close the open windows.
Restart your system.

Enter BIOS setup.
Disable anyunused ports that you removed from device manager.
Under PCI / PNP, enable update configuration / ECPI.
Save and exit setup.

Complete the boot process.
Windows should automatically re-assign IRQs to avoid conflicts.

Shut down and boot up 2 more times.
Verify that the IRQ conflicts are corrected.

Go back into device manager, and re-enable IRQ steering.

You can share IRQ with another device,but in your case with the conflict yo may want to check for an open IRQ to use
Click Start->Settings->Control Panel,double-click the System icon,select the Device Manager tab and then click Properties
Witin view Resources tab,click IRQ
Note any open IRQ's not being used

Within the Device Manager,click on the Video card
Click Properties
Select Resources tab
Click the Setting you want to change and select change setting,select IRQ and then click OK
Some of the IRQ's cannot be changed,once IRQ is set click OK

I was unable to resolve the conflict with the answers provided. It turns out that the PC in question also had problems with the onboard sound card, and I had to replace the motherboard. Thanks for your time in answering the questions.
