BSOD in FSX every flight

Hi all,

I'm an enthusiastic flight simmer and I've just upgraded to a new powerful but expensive system. Unfortunately I have not much experience troubleshooting computers, so please be patient with me. I didn't build the system myself, but the manufacturer overclocked the i7-4960x processor to run at 4.3 Ghz in turbo mode. The new system is great, no stuttering at all and high frame rates as expected but the frustrating thing is that I get a BSOD in almost every flight when playing FSX. Sometimes this happens immediately after firing up FSX, sometimes this happens 7h hours into a transatlantic flight which is even more frustrating... Because I use this computer exclusively for FSX I cannot tell whether the BSOD would happen in other situations as well. The computer is networking with 2 laptops, another desktop and a tablet, all of them running add-ons when I'm flying. I conjecture that the BSOD is related to the overclocking with which I have no personal experience at all, neither have I run any system stability tests on my own. I desperately need help but please take into account my low level of knowledge and experience when trying to help. Thanks a lot in advance. I have collected all .dmp files in the attached zipped folder.
