I found three IRQ conflicts on my machine. They are as follows: Problem Devices PNP Device ID Error Code IRQ Holder for PCI Steering PCI\IRQHolder\IRQ08 10 IRQ Holder for PCI Steering PCI\IRQHolder\IRQ0A 10 IRQ Hokder for PCI Steering PCI\IRQHolder|IRQ09 10 I found this under Systems Information under sub-directory problem devices. Any ideas on what this is and how I go about fixing it. My machine has a mouse with a mind of it's own which leads to machine lock-up.
