original title: IRQ troubles.
Computer decided to assign video, audio, and network cards all to one IRQ. Problem is that when more than one of these is in use, performance degrades very noticeably.
Option is grayed out in Windows.
No option in BIOS.
No free slots to switch cards.
Uninstalled/reinstalled drivers to no effect.
No onboard video or audio and can't use wired network.
How can I change the IRQ?
