Windows Hangs after Soft Reboot

Yesterday my otherwise-stable XP box started hanging at the Windows splash screen,
but only after a soft reboot, e.g., after choosing "Restart" from the XP shutdown
menu, or after hitting the reset button on the box. The hang occurs regardless of
whether I'm booting in Normal Mode or in Safe Mode, and regardless of whether the
restart was invoked from inside Windows XP or from a DOS program It appears that
as long as the system boots from a soft reset XP will hang at the splash screen.
Booting in Safe Mode reveals that the last system driver loaded is mup.sys. It would
appear that XP is hangning while attempting to load a device driver.
The only way Windows will boot is after a cold start (i.e., from a powered-off state).
I've examined the ntbtlog.txt boot log file from a successful (cold) boot but I see
no indication that anything is amiss. No boot log is created on a failed boot, which
means the system is hanging before the initialization of smss.exe.
The last thing I did before this problem started was to install the driver software
for my Nokia DKU-5 USB interface cable. Since the problem started I have uninstalled
the driver using the program's own uninstall routine, but the soft reboot hang persists.
As the problem occurs only on a soft reboot it's reasonable to assume that either
the RAM or the BIOS is at fault. I tested the RAM with one cycle of Memtest86+ but
no errors came up. I have yet to reset my BIOS defaults, but I'll do that next and
report back.
In the meantime, I'd appreciate any input anyone may have on the matter. I can post
the contents of my boot log file if anyone wants to inspect it.
Thanks,
Piyono
