So, my new power supply and graphics card came in today. I got them, installed the power supply. Started it up, worked fine. Installed the drivers from the disk onto my PC. Then places the card in. Started the PC, resolution was messed up and I cant even use certain resolutions. However, my games wont even start. Teamspeak, Google Chrome, everything else runs fine. But my games will start, pop up with a black screen, and disappear off my task manager. I just got the Radeon HD6670, I was on integrated graphics. Help?
