Hardware out of date, Flash Player locked, Tabs across top, CP

My Internet Explorer program died. My repair shop installed Google Chrome. Now it is sending me crazy messages...."This computer will no longer receive Google Chrome updates because it's hardware is no longer supported". .....#2 "Adobe Flash Player was locked because it is out of date." 3. When I open the program it has a bunch of "tabs" all across the top that say "loading". I must have goofed up, but don't know how to fix this! If I take it off my Control Panel, can I download it over again or does that removal take me off the internet? Thanks so much. Corny
