Well, I got my AW 18 on Monday and am having the exact same issues! And we're not the only ones. I've found other AW owners who have had this going back to August. Like you, I haven't had any issues with games (Far Cry 3 and Crysis Warhead) yet but then I've had it less than a week so haven't loaded any except these two. With one person, I'd say ok, re-image the drive. Two people having the problem starts to sound like something else. Three+ indicates a systemic issue that goes back to AW and Dell. I'm still troubleshooting through msconfig.
