System Interrupt Controller

[Mintoo]

I did an upgrade of my motherboard recently, memory and CPU and also did a clean install of Windows. It was working great with some minor issues that was soved by me easily. But now I am seeing some stop errors with no regularity and not enough to prevent use of the PC. I checked at the event viewer log and I dont know how to interpret what is in there. I also went to a KB article and read what the errors mean. One of the error said that the ACPI BIOS in the system was not compliant with the ACPI specification, so I updated my Bios which was three versions old already. There was also some message about the Command Antivirus, that I dont have installed now. There was also some entry in Device Manager with yellow mark under other devices System Interrupt Controller and Usb Universal Serial Bus Controller. I solved the USB issue by updating Usb drivers with VIA 2.0 USB software and it went away. But I dont know anything about System Interrupt Controllers. So can anyone please help. Thanks

Have you tried to install the motherboard chipset and all other drivers that is supplied on the motherboard CD?

Thanks for the reply. I used the mobo CD and it worked properly. I was thinking that the drivers for hte disk were for Via Sata and hot plug functions only.

Actually whenever you do a clean install then you always have to use the mobo CD to install the motherboard drivers.
