Bought the base model santa rosa Mac Book Pro a few weeks back (2.2ghz, 2gb RAM, 128mb VRAM), and am having issues with random lockups in World of Warcraft... I thought it was heat-related, so I installed SMCFanControl (4000rpm) and added a Targus ChillPad, but it still happens on occasion. Basically the UI freezes, but the soundtrack still plays, and sometimes to mouse continues to work (haphazardly, jumping all over the screen), but mostly the mouse/keyboard is dead too. If I wait several minutes I get booted back to the login screen with a "disconnected from server" message. Anyone else experience this? Could it be bad RAM? (suggestions for eliminating possible culprits?) P.S.: am usually running in closed-lid mode (although yes tried open lid mode too) with an external 22" monitor running at 1680.
