Missing Module

My problem started with a quick DOS message saying an application failed.

This occurred as I was loading a game disk ( warlords ) that I've played for

years on this PC. The PC will no longer autorun the disk. I had no Idea what

happened so I put in on my wifes PC and it ran fine. In the error log , over

and over it says " the specified module could not be found" How do I find out

what is missing? I tried to go back and restore the system. There six restore

points available, and not one of them would work. I have dissabled the

restore option for now. I've run spybot search and destroy, AFG and addware

and no errors found. I was going to try DrWatson, but my son used it and now

can't get it to shut down.. lol

Any help would be greatly appreciated.
