I think you are missing some things.
This is a brand new high end machine. Everything I do works great except FSX/FS9. But that has improved as well. I think I added to the problems by installing too many aircraft/scenery packages too quickly. I ran registry booster last night and found in excess of 300 errors. They have been fixed and FSX is now running at a smooth 30 fps without all the anomalies etc. I have had two lock ups, but only in the second or third flight in a row with the previous being an extended flight. I am still testing and I'm sure there are other tweaks that will help. I do not believe it is a power issue, especially since no other programs have shown any effect.. I have had FSX, Google Earth, Google Chrome, Fraps, and REX open at the same time without any indication of strain on the processor or the video card. I have run 3D Mark with no problems and a good score. Not the highest, but good. There is nothing to indicate a power or temperature issue. I have yet to see the temp exceed 31 C. On my old machine, I could not even run iTunes while FS was running. Now I run FSX, iTunes, Fraps (for screenshots), etc. all at the same time, with ease. And I sometimes forget that I had other programs open, like PSP, and again with no indication of strain on the processor or card. The only time I have heard it kick into turbo boost, was the most intensive part of 3D Mark and once when I was flying and listening to music and did not notice the time and AVG kicked in with a fast scan. Even that did not effect the sim. 

Oh, wait, you're talking about the computer. 
Right now, win 7 default, every Wednesday, but I think I'm going to change to daily. But every time I check it, there is 0% fragmentation on all drives. Thinking about getting O&O, but not sure the budget will allow it.

I believe you are aware that I not only have the shirt, but the coffee mug as well.
