I have a HD6570 1GB DDR3.One week ago the pc had some freezes that were caused by the drivers and a file called atikmdag.sys after uninstalling the drivers that problem disappeared 1 day the screen had some dots and lines at boot after the pc didn't start at all but if i put another card it starts. What can i do?
