This is one of those problems that is probably extremely difficult to diagnose, but I going to ask it anyhow, in case someone else has the same problem...

I have a game which runs perfectly virtually all of the time (honest!). Very occasionally the game will not run either from within WED or in it's published executable form. The screen just flickers to black and then returns to WED or the desktop. There are no messages, nothing. When this happens I restart (no effect), run Aquamark (all OK), run dxdiag (passes all the tests). Then, a few days later the game will run again - *and I have done nothing to the game in the interim*. Once I was showing the game at an event and it wouldn't run, even though it ran just before I left home! It was terrible.

Any ideas on how I can diagnose this problem?
