But ya I'm also running out of ideas. My plans now are to do a complete wipe of the display drivers and reinstall them, if that fails I will set up monitoring software and see how the cpu, memory and gpu behave on xp vs vista when playing ArmA and see if there is an issue there which may lead me to further steps, if that fails I will try a clean factory install setup, failing that I'll borrow a copy of vista from a friend to see if it's a Dell vista install issue. I may try a few other things in between those steps.

Why not try this and use windows 7?
