Do you have Norton products installed? If so, you'll need to run LiveUpdate. Their SYMEVENT was causing havoc and giving you that error. Also I would install XP SP2 because it has a better error reporting capability.I got the same error at work. It would either cause my comp to reboot or BSOD. After a week, Symantec updated their SYMEVENT and the Norton Redirector which solved the issue.

Here's Microsoft's take on the problem: http://www.microsoft.com/resources/documen...md_stp_ottj.aspMore info and user input here: http://www.tek-tips.com/viewthread.cfm?qid=308429And here: http://www.jsiinc.com/SUBM/tip6000/rh6045.htmAnd here: http://forums.winxpcentral.com/showthread.php?t=4653Hope this helps,Greg

no anti-virus program installed:-doh

"no anti-virus program installed"So, you like running around nekked? Not having some sort of AV on board could also mean you have virus('). Do a Google for Adaware, SpyBot, and (the best of all three choices here) SpySweeper.Good luck,Greg

I turned off my paging file and I think that did it.I ran the sim for over 30 minutes no crash ...

well back to the drawing board :-jumpy...it crashed againx(
