Thanks for the responses guys, I found out a little more today. Turns out when today I went into system information, I found a whole slew of things hogging IRQ 11. These devices werent listed under IRQ 11 before, just now they are. Here is what all it says under 11, Microsoft ACPI-Compliant system (and no the comp doesnt shut down correctly)Nvidia Geforce 2 MX, VIA Rev 5 or later USB Universal Bus Controller (2 of these) Kingstone EtherX Ethernet Card, Creative AudioPCI, HPT370 UDMA/ATA100 RAUD Controller. All of those items are showing IRQ 11 now, and before it was just the Creative sound card and RAID controller. The only change I have made is installing Roxio EZ CD 5.0 which I think could be to blame. Anyway, Intel is completely unable to help, and since a friend built the system I have no manufacturor to find out how to fix this from, so any help with this is most appreciated. Thanks
