ntkrnlpa.exe !KiUnexpected Interrupt+0x121

[Kris]

OnairGT HDTV program occasionally locks when changing from/to ATV/DTV such
ther the windows do not refresh and the only way to get rid of it is to
reboot. Other programs can be terminated normally.

Googling pointed me to nvidia so I changed from current 169.21 to guru3d
174.30 to try for a bit.

Searched C: for that module and find 3 copies:
system32: size 1968 date 8/4/2004
C:\WINDOWS\SoftwareDistribution\Download\dc3b8fb011c281dea1cb7a45f880da78\sp2gdr
size 2009 date 3/1/2005
C:\WINDOWS\SoftwareDistribution\Download\dc3b8fb011c281dea1cb7a45f880da78\sp2qfe
size 2009 date 3/1/2005

Those look to be 2 SP2 modules and wondering why they aren't in my
system32???

ntkrnlpa.exe!KiUnexpectedInterrupt+0x121
came from top of the stack,
from the top of the thread,
for the hung program (process explorer)

Any ideas as to
why I seem to have an older module in use? should I change it?
what is causing this hang?

huge tia!!!

add-on:
ProgramChecker says is's okay 5.1.2600.2180
Both avg sypware and avg a/v found no problem
MS KB didn't point to anything obvious to me for the module, and nothing
for the interrupt message.
