Any ideas on why all of the sudden the icons on my desk top are either in half or have fuzzy lines going through them. If I click on them the return to normal, but then the one I had done previously gets fuzzy again. Also, on my task bar some of the items don't appear until I put the arrow on them. Even my start button is fuzzy until I click on it. Any suggestions would be appreciated. FYI this is about a three week old Dell. Thank again.
