I have a dell xps 8300 that i want to install a Radeon 6670 in. It will boot...display and let me log in...then i work for a few seconds and the whole machine locks up. I have to force power off to get it out of the lock. I have tried all the drivers I can find for it...im running windows 10 pro. If I let windows pic the driver....its the Microsoft default....but it still locks up the machine after a few seconds
