IRQ issues

[HavocXphere]

I got my new PC and all is well...except the IRQs. I'm getting mad conflicts that make UT2004 unplayable.

I checked the IRQs and sure enough *everything* of significance is piled onto 4 IRQs while the unused ps/2 and COM ports have one to themselves each.

The applicable options in the device manager are all greyed out. So how do I changes them?

Also, are there any hidden IRQs, i.e. numbers that are used by the system internally but are not displayed in the device manager.

ETA: Is there a way to figure out into which of the billion USB controllers the cordless desktop is plugged in.
ETA2: The PnP option in the BIOS seems to have something to do with this, but I'm not quite sure what.

Thanks

lol i have not had an irq conflict in 10 years or so therefore will be of no use in trying to help but post your whole spec anyway (someone will ask if i do not)

Hmm, I suppose your right, its probably not really a conflict per se. I know they are supposed to share IRQs, but not like this. In UT the keyboard+mouse combo cuts out every few seconds, sound distorts when I do something intensive in windows etc.

Found the list of IRQs at Device manager==>View==>By Connection

Screenshot of the problem.

I should have checked them on my previous PC too 'cause they obviously have a bigger performance impact than I though.

Don't the chipset properties share interrupts? Is it the device manager that's telling you there's a IRQ conflict? Are you running the right drivers?

I think I've found the problem. I haven't yet formatted since I got the new hardware.

This suggests that most of the IRQ stuff is configured at install time and can't really be changed afterwards.

I'll format later and report back.
