Help with determining the registry entry/process causing my problems

My os is windows 7 professional 64 bit and have been using the computer for about a year with no problems until now. I am having problems with several programs, and I suspect that because I started having problems at the same time it is either the registry a process is causing the problems. For the 3 programs below I have tried to reinstall the programs, do in place repairs, and I did a repair install of windows 7, with nothing getting fixed. So, I am at a loss as to what to do next, short of doing a clean install (which I would prefer not to do).

So, if anyone can help me I would gratefully appreciate it.

The programs that are not working properly are outlook 2003 (it crashes when I try to open the calendar),

the event viewer log says:

Thank you in advance for the help anyone can offer.

Just to add the other things I tried but did not mention (as best I remember):

selective startup: no changes
Safe mode: no changes
trying to repair outlook, I tried:

safe startup
detect and repair
scan pst tool
outlook /cleanreminders, outlook /resetfolders

Thanks for any assistance

also:

a system restore to before the problem started
and a malware/virus scan

again to no effect.
