Hello. I really need some help from someone please. So here is the problem..... very frequently when I am watching videos (netflix, abc.com) the computer crashes. Sometimes the screen just goes black, sometimes black with a one inch cubed barcode, sometimes horizontal colorful lines, sometimes a blue screen. (Not really sure if the appearance of the screen is relevant) However, this is a very annoying occurance and I do not understand why it happens. I have been told it sounds like a driver problem. I have checked for updates for my ATI driver, but it says they are up to date. Any ideas would be helpful??? Thanks
