  1. Generally speaking if you have changed something, in your case upgrading the memory the chances are any issues you get soon after could very well be linked.
    First thing i would check is if its actually compatable with 4gb of memory. Laptops usually are a pain to try and upgrade the graphics, more often than not its not possable. With your machine i would be very doubtful that its possable.
