I just got a reference Msi 6950 2Gb card, I installed the 12.4 drivers. rebooted. then downloaded the techpowerup atiwinflash, 6970 bios, I do it all correctly, load program, then reboot. 6970 says it flashed fine and even says verified like it is supposed to, after reboot though it just a black screen when it loads up to windows. I can hear windows at the login screen and everything... thoughts?
