HD 7950 drivers black screen opening game

I have a new graphics card, I'm relatively new to all this hardware updating, but I've followed guide and managed to install the thing. Problem is, I'm never sure if it's going to function properly. I updated the drivers to the most recent and every time I open a game I get to the first logo screen and once it is supposed to go to the next it fades to black, like normal, but gets stuck there, my computer is frozen completely and I have to hard restart. I also can't go into the catalyst control center. When I try to open it, I get a grey screen with vertical white lines. Sometimes it's orangish, sometimes other colors. The same thing happens when I go to a store page on the steam client, but only when it has the video player, nothing happens when it's on browser. I uninstalled my drivers and installed the beta drivers. No problem there, for a day, then it started up again. Then I went farther back (current is 13.9) and no problems, for a day, now it has started up again. Oh and it's probably important to note that when there are no crashing problems, the game runs perfectly smooth, no crashing, no nothing. Oh and last night I was able to play games, but not go on store pages. Help!
