It's really hard to know without more information about your system and what you did.
Here is one mildly contrived way to produce the result you describe:

<< Version5`Graphics`
$DisplayFunction = ToString;

enter image description here

If that is indeed in code you ran you can, as J.M. comments above, restore this with:

<< Version6`Graphics`
$DisplayFunction = Identity;

    $\begingroup$ @belisarius I don't feel like having to edit every reference when he updates his name. Sorry if it's confusing but frankly "Guess who it is" is confusing anyway IMHO. $\endgroup$ – Mr.Wizard Jun 19 '15 at 3:57

    $\begingroup$ I promise to change my name back when my Gedanken Mathematica license expires and I can use the usual version regularly again. :) $\endgroup$ – J. M. is away Jun 19 '15 at 4:03

    $\begingroup$ @Guess I think we all await that day eagerly. Your Gedanken clearly works better than mine, by the way. $\endgroup$ – Mr.Wizard Jun 19 '15 at 4:06
