ATI Radeon HD 7950 black screen GSOD

I got my graphics card a few weeks ago and off and on I have been having crashing issues. Whenever I open up a game it loads the company logo, fades to black, then freezes on the black screen. Also, videos on tumblr crash my computer after i click play, even playing videos on steam client store pages crashes it. Sometimes those crashes are a black screen, sometimes a bluish purple screen, sometimes a screen with vertical lines. I even reinstalled windows to see if it would fix it, and after about 2 days the problems came back. the really odd thing is that I don't have ANY problems if I uninstall and reinstall the drivers, but after about a day or two the problems come back. This can't be a hardware issue can it? I also got a green screen just now when opening up the advanced options on windows firewall. Oh and when I first got my card my computer would black screen after a minute but uninstalling private firewall fixed it. Could this be a firewall related issue? Maybe just a driver issue? Help please!

Edit: I just deactivated my firewall and antivirus temporarily and it didn't do anything, but I don't know if you have to uninstall or something so I don't know if that rules it out entirely.
