MODERN TECHNOLOGY ..... GREAT WHEN IT WORK'S, RUBBISH WHEN IT DOESN'T !!!!

After two weeks of being in the computer shop for repair, I thought that it was 'all system's go' again but, NO !!!! I went to write a new post, but my photographs will not load.....the add selected button will not work. Have any of you had this trouble ?............ HELP !!
