Additional troubleshooting data. The only driver that was out of date was
the Intel Network driver. I installed the latest version with no joy. Then
I went into msconfig and set it for selective startup. I turned off
EVERYTHING and still the system will not come back from a shutdown. So it
would seem that, as I originally said, it is not a driver or hardware
problem. It is a primitive problem in SP2 with my MB, CPU or chipset. Given
that the MB is ASUS, a major manufacturer, and the CPU and chipset are both
Intel, it would seem that some level of compatibility testing could have been
done. I have an e-mail into ASUS. Maybe tomorrow I will try a debug startup
so I can see where the system hangs. There are no significant events in the
system event log.
I'm about out of ideas.
Boot into safe mode, remove the device from the config (computer
management, device manager, uninstall), shutdown, remove the device
itself, boot system in safe mode - make sure device is not in device
manager again, reboot in normal mode.
Now, the device is no in your computer, go out and purchase a cheap (sub
$10) NIC from anywhere. Install it according to vendors instructions.
You could also try to put the old NIC back in, reboot, have it auto-
detect, but, DO NOT LET IT PICK THE DRIVER, manually pick the driver
from your new one you have.
Also, you might want to see if the "Intel Application Accelerator" needs
updated, I've seen this cause problems with older SP2 machines.
