FSX disappears without error!

[piacaptainmahad 0]

FSX disappears without giving any errors, mostly it happens when i switch it to window mode from full screen and vice versa. 
I've monitored VAS using process explorer VAS doesn't exceeds 2.8GB, and there is no crash report logs in Appcrash viewer neither in Event viewer.
I've tried re-installing fsx still have the same issue, sometime i get CTD fault module name were DINPUT8.dll and in other CTD fault module was StackHash_addc. but now there is no CTD, fsx just disappears randomly without any error.
tried all latest drivers and UIAutomationcore.dll stillno joy!
Specs:
i7 4790k @ 4.4ghz stock speed, 8GB RAM, Nvidia GTX 750

Try starting with the default flight.   It can be a good troubleshooting tool.  Especially after a new install.

Went to try ur suggestion and now when i run fsx it just disappears after running for about 5 secs, appcrash view isn't reporting any crash report, but event viewer has this message now :
''The Desktop Window Manager was unable to start because composition was disabled by a running application''
''A request to disable the Desktop Window Manager was made by process (Flight Simulator X v10.0.61637.0)''
I've no clue what's going on.

Have a look in here. An answer may lay within.

If there is no AppCrashView or Event Viewer log, then you did not have a crash or anomaly. You most likely ended your session by shutting down FSX. There is a known problem (bug) with switching between Windows. Are you using Alt+Enter to go from full screen to windowed mode? Do not use Alt+Tab or any other means to switch views.

 

Sometimes too, because of Windows memory issues, it takes a long time for the screen to show up. This indicates you are having memory problems most likely caused by the BufferPool tweak.

i figured it out that was Sweetfx causing fsx to quit without errors, but now i have CTD with fault module name : Kernel32.dll Help!

Well, in the AVSIM CTD Guide, under probable/known causes of crashes, there's an entry for the kernel32.dll, page 13. The list of probable/known causes was created based on research across the Internet for solutions to certain types of crashes. In other words, AVSIM did the research, you just need to apply the research to your issue.
