problem– the basic windows games,minesweeper, solitaire fail to work. get executable unable to run. at same time any on-line video clips will not execute, the log on music does not play(my tip that the PC has failed again) and at shutdown I get ” waiting for iexplorer to finish logoff tune, fdo you want to force shutdown”. I do a system restore and the PC is good for 2-3 days before it fails again. reloaded windows 7and all drivers, PC worked for 1 week before failing. I have been on the phone with DELL support for over 12 hours the last 2 weeks with no solution.
