Video just started crashing while gaming. I get lines across the screen, then blue screen with atikmdag.sys error message. I see quite a few people have this problem but I see no definitive solution. Because this seems to be common it appears amd/ati doesn't want to take ownership. Because this is happening to a lot of people, should even waste my time searching for a solution, or get a GeForce video card instead? I haven't seen anyone complaining of the issue with the GeForce brand.
