Screen freezes immediately after app opened

Question

Using iMac late 2009, 2.8 GHz Intel Core i7, 4GB 1067 MHz DDR3 using Mavericks Version 10.9.4 running ok since updating July 11th.
Today when opening Preview, Pages, Numbers, iPhoto, iMovie, App store etc. app opens as does application menu but then freezes entire screen.
Had to use force quit.  Safari ok but if opens in Preview can't do anything.  Tried reinstalling software without success.

Answer 1

I hope to have done as you suggested but hopelessly out of my depth.  Appreciate your help
