Hello, I just recently reformatted my computer and also put in a pretty much brand new video card xfx hd 6870. I built this computer about a year ago and haven't had any frequent blue screens up until now. It shows system service exception, while also displaying one of these two files whenever I'm gaming, dxgmm1.sys and atikmdag.sys. Also happens once in a while when I'm watching videos/movies. I installed the newest drivers for the card yet still get bsods and even on drivers released previously. Any ideas on how I can get rid of the bsods? Thanks.
