Hate to tell you this, but the surest way to fix your problem is to make
it crash on your PC also.  Then you can figure out why it crashed.

Find out what's different between your PC and these other PCs where the
game crashes.  And then emulate the differences on your PC.

What could be going wrong?  Not too many things.  If your game don't use
anything fancy, you should be able to diagnose the problem by comparing
the OS, OS version, video card, video driver, sound card, sound driver,
memory size, mamory manager, memory configuration/optimization, TSRs.
