Also...just thought I'd add in that on the odd ocassion I get a blue screen with a different error message which mentions an ATIxxx file of some sort...so I can only assume this has something to do with my graphics card (ASUS 9250). I do know that my graphics card and some USB ports are sharing the same IRQ....16. I can't change it though...as it seems to be fixed. Do you think this sharing of IRQ could be causing a problem? I have disabled my two onboard serial ports and parallel ports to free up IRQ's, but somehow that doesn't seem to have made a difference.

ANy thoughts?
