Hmmm...I've looked on many forums, and it seems that the vertical stripe problem for the 5000 cards is pretty wide spread. Its strange, instead of crashing with a blue screen, it crashes with the vertical stripes... I can't get prime95 blend to run without bringing up the stripes (it doesn't happen in games). Anyone else have the vertical stripes problem? Anyone know why/how to fix? I have a sapphire 5850.
