My computer has several conflicting IRQs, which I think may be causing some instability in the system. I would like to reassign the conflicting IRQs to unused slots. However, when I open a device's properties from Device Manager and go to its Resources tab, the option to "Use automatic settings" is disabled/grayed out. Is there another way that I can change the IRQ assignments? I am using Windows XP-64 Pro. Thanks.
This is disabled because Windows automatically and successfully installed the device without conflict.
can you be more specific? which device? a screen shot of the device manager maybe?
