Flight Sim X hangs

Whenever I try to save the game hangs and locks up the pc completely. Pentium D 2.8 overclocked 3.2 nvidia gts 8600 4gh ram What else do I need to make this work??

I recently had similar trouble running FSX that I was able to resolve. My issue was the game would load but then I'd get BSOD when I tried to take off from the runway. I thought it was my video card and/or driver but wound up being my audio driver. Things I tried in my process that you might consider doing:

--Download the FSX SP1 from Microsoft's website; it's supposed to improve game performance.
--make sure your video and audio drivers are up to date.
--make sure your RAM isn't defective. Download the Windows Memory Diagnostic from Microsoft, run it from a floppy and see if your memory is bad (mine was!)
--Try a utility like FSAutostart that allows you to set a configuration for running games; it lets you select what programs and services to shut off before running a game and even gives the option of restarting them all after you exit the game. nice because you can set up as many different configurations as you want, so if one service can be stopped with one game but not another, then each game can have it's own config routine in FSAutostart.
--If all else fails take it back and get Microsoft Flight Simulator 2004 Century of Flight; the reviews I read stated it's about as good and runs better and on a lot less hardware than FSX.

Good luck!

Thanks for all the info! The sim runs like a champ until I try to save....even with all the setting maxed.. I appreciate the info
