Oh thats great, so I might as well throw the damn thing off the balcony

Ive had the machine since 07 I believe, and never had much issues with it until recently. I get lines on my screen (different positions when I restart), as well as some other visual distortions. Id go on Facebook for example, or yahoo IM, and type to my friends, and some of the letters would delay before they would show. Now it likes to freeze on me from time to time, almost daily. I dont have that many programs on here, and could just re-install them, but Im wondering if this will do the trick.
