I recently upgraded my PC to a fairly hot gaming machine and Flight Sim X crashes constantly.  I've been told I need a Win 7 PC to run Flight Sim X, but I have to think that Win 10 can do the job, or perhaps there is a shell program I can use. 
My new machine is:
Intel Core i7-6700K @ 4 GHz with 16 GB RAM and an NVIDIA GeForce GTX 1070 with 8 GB VRAM. 

I would appreciate anyone's input as Flight Simulator online with VATSIM ATC has been a huge hobby since the first version of FS came out in the late '80s.  I would love to get back in the air. 

Thanks,
