Thank you all for your input. After reading your opinions, maybe I will re-install P3D.
However I disagree with the opinion that LM couldn't care less if users like myself are imposing on their time for pure entertainment. On several occasions under IFR I was given nonsensical heading changes over and over again. As if I was being slapped on the hand like a child stealing cookies. On the last flight before PC "crash" , I was given nonsensical altitude changes eg: "climb and maintain 8,200" which as most of you know is not a common en-route altitude one would expect from a real ATC. And as soon as reaching 8,200 , it was immediately followed by "...descend and maintain 7,200...."???
This went on and on for several minutes during this flight. It's as if LM V-ATC was saying..." if you want to play "games" , we will play the "game" too" And then when they got tired of playing , they infected my PC as punishment.
This PC was serviced by "Micro-Center" computers & electronics in Denver. They had this PC in their shop on two occasions and NEVER found any fault with the hardware. They could not find any CLEAR reason for my "crash". Or , why the recovery disk failed to fix the issue. They offered two possible explanations; 1) File corruption during WIN update. 2) Somehow a virus had gotten through my WebRoot firewall in spite of this PC being a dedicated Gaming PC and was rarely used for Web surfing.
Of course "Micro-Center" completely quashed my original accusation that it was their own in-house diagnostic program that either corrupted my files or injected the virus infection.
Anyway, thanx again and I will no longer bore this community with my "problems". However, you might want to make a mental note about this in case this becomes a more widespread issue in the future.
