System 32 File Problem

I am running Windows XP Home Edition and am having a problem at startup.
When I boot my PC, an error message indicating that "Windows is having a
problem with a file named bselmco.exe and must close" appears. When I close
the error box, everything usually runs fine.

However, this morning I could not get my PC to run IE properly or even boot
to the point where my Taskbar would appear so I could use Quick Launch to
run dial up the internet and use IE.

I have also had a problem recently with the taskbar flickering on and off
and eventually the Active Desktop Restore screen appears. When I click on
restore your Active Desktop settings, everything runs fine. I have Active
Desktop disabled as my default setting.

I did a search to find the bselmco.exe file and it is located in
Windows/System 32 folder. How do I repair this file and is it related to my
problem with Active Desktop?
