Hello everyone. I have been running into a sporadic problem with my new i7 930 build of FSX (see my signature for specs). Sometimes when I go to an external view of the a/c, the screen turns into one color (which varies in solid color that averages what the sky color is at the time), and the system freezes. I have to hard reboot the computer to get out of it. I used to have this problem for some time in my old system (which used the same video card), but it would only occur if I was doing a tower view. Now, it happens during flight when I switch to spot view, any view outside the a/c. System was set up with NickN's guides as the bible, with Nhancer controlling AA. Nvidia Driver is 197.45. I know, I should be using 182.50 like most people use but I have heard good things about the newest nvidia drivers. I remember having this problem with 182.50 in my old build as well.I did some research and others claimed it may be a bad monitor cable or videocard overheating. I actually just bought a new dvi monitor cable to see it it would solve the problem, but it didn't help. I never overclocked my vid card, and the gpu fan is running when the crash occurs and the temps seemed normal.In the old system the problem eventually went away, I don't know how. Has anyone run into this situation? I may try running the older 182.50 driver to see if that alleviates the issue.

Well, I switched back to the 182.50 nvidia driver and for the most part the problem disappeared, or so I hoped. I was on a long haul pmdg 747 flight over the Atlantic in cruise, away from the computer. I come back to my system and found it locked up all in a shade of light black (because it was night, so it matched the color of the sky). The strange thing about this is that I was in the VC in forward view, I didn't change views at all (which normally causes the problem) Last year I ran FSX on winXP 32 bit and never had this issue, so I wonder if its a winXP 64 problem.As before, the sound is still on but the computer will not respond to alt tab or ctrl alt delete, so I have to do a hard reboot. Is this likely to be a heating issue if not a driver issue? My CPU is overclocked to 4.2ghz, and it has tested stable and at less than 65c at full load in stress testing with OCCT and Prime95. GPU is NOT overclocked. This is not a frequent issue, but its annoying nonetheless. Can anyone weigh in with some advice?
