Ok my friend, thank you for your help. Hope to the next long haul Flight not crashed.....

Again crash!!!.....afte all these changes....my flight crash!

All that steps was helpfull in the pretty much same situation: http://forum.avsim.net/topic/407468-ctds-with-ezdok/

 

I posted the link so we can check if we missed someting

Crashes after long flights (like 3 hours) can be due to overheating but I think the most important fix was the one suggested by B247NG to install the fix at the following - - apply this patch: http://support.microsoft.com/kb/947246.  If you did that and you are still getting crashes, then your system must be overheating OR a CPU/DRAM voltage setting is too high or too low.  Since it does not appear you are overclocking, then it must be overheating.  Reducing your fsx settings will reduce some overheating.  FSX is very CPU intensive and, if it is overheating or has a too high/too low voltage setting, FSX will crash.

 

Best regards,

Jim

i ll try to reduce my game settings,,,,,and test again...
