New to the forum and tried looking around the past few days but cant seem to find a solution to this issue. I use to be running just a 7950 and 280x for a few weeks as I just got into the mining world, Everything went smoothly so I ordered a few more 280x's to get another full rig setup but every time I try to open qtminer to start mining as soon as it trys to start my computer will throw a bluescreen of death with the atikmdag.sys error. From my research that's a driver issue for the card/s. I spent all day trying different driver versions ( 12.x - 16.x ) as well as reinstalling windows 7 twice and still have the same problem. Before I reinstalled windows my computer would not even show display when booted with 4 cards, after a reinstall its now showing display and all with all 4 cards hooked up but will bsod when attempt to mine. Does anyone have any ideas on how i can get this working again? Anyone that can assist me in getting all my cards mining will be compensated for the time and help.
