My only bad experiences stem from my screwing around with the BIOS. Maybe if I did not screw around with voltages or timings in the first place, I would not have any problems at all.
Oh and Civilization V is a crash prone disaster but I do not blame Microsoft for that one. How could I? It is either nVidia in its post-266 drivers or Firaxis. The feature set in 273 is too rich for me to revert back to an older driver version. Maybe 280 will come out this month and resolve it. That still has not prevented me from spending over 600 hours on that game.
What about my web browsing behaviors? Sandbox and restrict plug-ins. Javascript is nasty but if it is not running what happens?
I will continue to spend ungodly amounts of time in Windows 7 while my Mac gathers dust.
Maybe I have said too much.
