Start Button displaying but not working


The start button was working until there was a forced reboot (power failure). Then left click (normal click) over the start button does absolutely nothing. Right click brings up a menu but "programs" and also "settings" are missing and not included on this list. Search or Task View buttons do not work either with "normal" click. Does anyone have any suggestion or fixes?
Thank you in advance *Huh
