Graphics Problem with FSX and Normal Cockpit Mode

Hello guys! I am an avid FS SIM player and have been playing since the FS2002 days.Currently I have FSX installed on my comp updated to SP2 (SP1 already installed).Anyways there is a somewhat major problem when using the regular cockpit or clicking menu items that is really discouraging me from playing the game which I love.The problem is that when I switch to normal cockpit mode or move my mouse cursor over an instrument to see its description, often the screen will go white and red and the game will get stuck for a few seconds and then unfreeze, its very unnerving and a game play breaker because it happens every time I change views back to the normal cockpit. The problem as occurs while not as often when I click a menu item while flying when I exit the opened dialog (map, realism settings, payload, fuel, etc...)I am using Omega 7.12. The problem has occurred while using all sorts of drivers official ATI ones and Omega's and several Windows reinstalls.Thanks for any help-Kris
