Hi Russ & Others
Have you tried different version of motherboard drivers. I have seen this
with VIA chips on the motherboard. I would start with the newest version of
VIA 4 in 1 driver until I found a winner. If that does not work I ran into
a motherboard with VIA chip also that needed the ACPI turned off. To do
this, I needed to turn it off in the OS and then off in CMOS bootup. It
maybe worth a try.
Good Luck
