Ok , I will continue until we solve this matter . I am not a technician , but I have solved the same problem and a few more by hounding it out. Now ...........You have upgraded the drivers , video card and etc but did you try to reload the discs one more time ? It should not take 4 hours to load with your laptops specifications. So I would start there . Load the discs with out anything else running if you didn't before if you did great. Did you register the software ? I think some how this counts but I don't know why. You never mentioned the name of your Operating System . Also check your color quality setting mine is set for 34 bit. If you are getting annoyed I will stop , but I don't mind trying to help you .
