FSX Crashes when pressing instruments

[clouds]

Hi Guys does anybody know why my FSX crashes when I am sat in the cockpit and I go to say turn on the pitot heat the whole game freezes and the pc re-boots. The game itself works fine this only happens every now and then. I get decent fps using a radeon x1950pro card with a 3gz p4 processor i just dont understand it. I have even started to use alacritypc which closes all programs before the flight sim starts.
any ideas would be much appreciated
cheers :-/

You might be closing something that you should not close.  8-)

Thanks garymbuska it does it when I dont use alacritypc also so I dont understand I also get the cockpit view going light blue sometimes as if the shaders cant cope.

All Alacrity PC does in my experience, is shutting down explorer.exe, and not really anything else. I still had to shut down a lot of processes manually, before I started.

And I didn't really see any improvement :-/
