Hi, I've got an Asus P5N32E-SLI motherboard and have Vista installed. I keep getting an error in event viewer for: "ACPI BIOS does not contain an IRQ for the device in PCI slot 21, function 0." This error repeats in succession for PCI slot 3,6,7,19,20,21,22,23,24 every so often. I've heard that the 680I chipset has been having Vista problems, but I was wondering if anyone has found a fix or at least a reason why I keep getting this message as I am not sure on what this error is referring to. Thanks and here is sample text from the event viewer if it helps.
