SPOOLER SUBSYSTEM APP STOPPED WORKING

This morning, I just started getting a nastygram at startup - "Spooler
subsystem app stopped working and was closed". Rebooted, but then CHKDSK
ran and made some changes, but the same 'Spooler' message displayed again.
CHKDSK may have run on the initial boot, but I missed it. Also ran an Avast
scan which found 2 corrupt (missing cluster) files & 1 corrupt Java file.
Avast couldn't read any of the 3.

Another peculiar thing happened this morning - the taskbar, which I keep on
the left (vertical) side of the Desktop, had spontaneously repositioned to
the right side.

I installed Vista SP1 yesterday (. . . connected to the nastygram?) and did
a couple of reboots then without problem.

Note: all of this happened after reinstalling Vista (Home Premium) from the
Recovery drive.

Any ideas about fixing the 'Spooler' nastygram?
