I'll have to rummage around the case when I get a chance to see which cards are plugged in where, and see if I can easily put the Matrox on a different IRQ. 10 perhaps? PCI slot 1 shares IRQs with the AGP card. PCI slot 4 and the USB controllers share an IRQ.

The USB hub on this thing has always been more flakey than I'd like (I usually reboot after using the 6-in-1 reader with my MemoryStick to make sure things don't lock up, etc.).

I may try removing the SB Live card and even the USB stuff and see if that helps.

Thanks for putting me on this line of attack. It may take me a few days to try these various things. Please keep any suggestions coming.

Cheers,
Scott.
