Hi Felix, thank you. ------ It used to be pretty typical for PCI slots to share IRQs with onboard devices. Take the sound out of slot three and put something else there, and most likely the something else will also share IRQ 17. Whether in newer motherboards anything might have changed regarding IRQ sharing I have no idea. ------ I do not know if the problem can be originated in the fact of having the same irq. In the BIOS Setup I did not find any option to change irqs. Maybe an option could be to try to update the BIOS, if an update is available. This PC is an IBM ThinkCentre Intel Celeron 2.66GHz.
