I was having the black screen with the drivers I installed with cd for Sapphire r7 260x oc 2gb edition. I uninstalled the cd catalyst drivers and didn't know I installed the same drivers from web site. I was okay for 2 weeks than black screen came back. I forgot to uninstall the older drivers. Than I installed the 13-12c-w7 catalyst newer drivers this time. Did I mess up. Should uninstall all the catalyst drivers and reinstall the newest drivers?
