My relatively new acer 7739 running windows 7 home premium has suddenly started experiencing problems, windows defender has vanished, calculator mysteriously dissapeared, & network troubleshooting no longer starts, I've run all virus scans - no threats detected, I have not been brave enough to do a system restore as I don't know where to restore it to, searches on google offer suggestions that don't work, laptop did not come with disks, so I don't know if I can do a reinstall, anyone have any ideas please.
