    Alright, so I am in need of some major help. First the tech specs, it's the all white version, not the newer aluminum ones(http://support.apple.com/kb/sp16). We bought this Mac roughly 4 years ago, have used it and has run like a charm since. As of about 1 year ago, it started becoming a little laggy and very small graphic glitches. For the past 3 months, it's gotten a lot worse, and after upgrading to Lion a few weeks ago, it has gotten horrendous. Giant graphical glitches across the board, and very slow and laggy. The only modification we have ever done t o this computer was put in extra ram to cooperate with Lion.

    Hi,

    Did you tried removing the extra RAM if the problem still persists?

    If yes, you have an issue with your graphic card... If not, your extra RAM is defective.

    It's not the RAM, as I have had this problem before upgrading my RAM and it's just been getting worse after installing Lion.
