I updated my driver the other day on my radeon 4850. I believe it was 12.10
Everything seemed fine but when I came back to my computer later in the day it was frozen. So I restarted the computer and on startup the monitor stays black and wont display anything. It isnt the monitor or the cable because it works on another computer. It could be another hardware issue, but I assume it is because of the driver I just update. I cannot get onto the computer to try to change the driver because I cant even get the monitor to display anything.
It could be related to my motherboard, but it happened on the day that this update occured so I believe it is because of the driver.
