I am having an issues When i open up LR on my Dell Inspiron 7500 the screen will go "blurry" The whole screen get digitized lines. They remain even after I close LR. Once I restart... Things are fine. No other program (PS, Chief Architect, video players, ect) cause this issue. Only LR.

Make sure that any graphics drivers you are using are up-to-date. If that doesn't resolve the issue then go to the Lightroom preferences, performance tab, and uncheck the "Enable graphics processor unit". Does that solve the problem?
