Strange Display In all online applications

HELP!! I have Windows XP and months ago I was altering my settings in control panel. I clicked on something and pressed "apply" but I cant remember what it was, suddenly my backround went black with white, large text and all windows I opened were the same... I manually reset my backround desktop thingy etc.. and all is nearly back to normal except my outlook express and all internet pages where often text is too large or it all overlaps and there are not any normal buttons or anything. I have tried resetting as many things as I can without loosing too much stored info... I definately do not have a virus on my computer... I have looked through everything in control panel to try and put right what I did but I cant!! Please help me to get everything back to normal!!

 

Maybe this. In IE, click view>text size. This setting will also have an effect on OE.

 

If you have a wheel mouse, with Internet Explorer open, you can also hold down one of the Ctrl keys and spin the wheel. Towards you enlarges the text, away from you shrinks it.
