RE: PC "gets stuck" entering Standby after SP2 installed

One thing to add - I saw another post about standby problems in which it was
noted that how long the PC had been on was a factor. I think I'm seeing
something similar. Right after a reboot, standby works, but after the PC has
been on a few minutes, standby only works intermittently.

Standby mode worked PERFECTLY for years until SP2 was installed. After SP2,
the PC sometimes "gets stuck" ENTERING standby mode and has to be rebooted.
When it gets stuck, the monitor is in power saving mode, the fans are still
spinning and it doesn't respond to the keyboard to come out of standby.
In terms of troubleshooting:
- I have a clone of the boot drive made just before SP 2 was applied. When
the PC is booted off that disk, standby works perfectly.
- Diagnostic startup: Behaves the same way - standby doesn't work reliably.
The problem is apparently not a video driver or something software (other
than O/S) related.
- Diagnostic startup with all unnecessary H/W (such as USB devices) disabled
in the Device Manager: still doesn't help.
- BIOS settings: I tried all possible combinations of power related BIOS
settings, but this didn't help, either.
I haven't been able to find anything useful in the event logs, etc. and
there's no crash dump.
I have the latest video drivers, etc., although this is a moot point if the
diagnostic startup doesn't work.
In summary, the only thing that correlates with standby not working is SP2...
Any ideas how to troubleshoot this? Is there some kind of trace output that
can be captured as the PC enters standby to see where it's getting stuck?
