My 2002-vintage computer has a recently-installed CPU and LCD display.
The computer locks up with the display pivoted 90 degrees via
irotate.exe while playing AVI files using Nero ShowTime, producing a
medium-high-pitched sound. The lockup seems to happen only when the
display is pivoted. Nero ShowTime is the only program I have which
will show AVI movies while the display is pivoted.

The last time this happened, CPU temperature was 43 degrees C and CPU
utilization was about 30 percent.

I reset the computer to recover from these lockups, only to find that
CPU hyper-threading is disabled until I restart Windows, which runs
very slowly, and then restart the computer and Windows again.

Does anyone have suggestions about how to stop this lockup while the
display is pivoted?

Anything in the Event logs? I don't think you can get to this point in
Safe Mode, but it might be worth a shot.

I'm guessing that you have a driver conflict between the video driver
and Nero. And either going to newer or older drivers (both Nero and/or
video drivers) might be the way to go.

You could also try that Performance slider under the Display Properties
as well. As that would probably fix it, but changing the driver(s)
version(s) would probably be better if possible.
