When starting my pc, the usual desktop with icons remains empty. The toolbar is visible and when i press on an icon they will enlarge to thumbnail size. When i press angain to enlarge, the thumbnail disapears. I cannot get into any program, settings, computer management or backup restore programs. This problem is occuring since tuesday morning. Monday everything seems fine. Has anyone got any ideas how to resolve this problem. I ofcourse tried te soft reset, onoff button for 15 secs as well as unplugging.
