I put this in the gaming section cause it only seems to happen immediately after leaving a game. Im running XP pro, and its happened a few times now, after closing age of empires 3, and i think swat 4. Screen returns to the windows desktop, but nothing will work. Mouse moves and sometimes changes to hourglass to indicate some sort of activity, but i cannot click on anything, and even alt-ctrl-del doesnt work. Task manager will not appear on screen. Only thing to do is turn the power off, anyone any experience with this?? Cheers
