Hello everyone, Recently I've purchased a new graphicscard, with a Radeon HD6870 GPU. Naturally, I tried to install it. But, after running into a few different problems, I rebooted my PC with the 6870 in it, and every time I do this now with the 6870 in it, it gets stuck on the Windows 7 loading screen. (See SS below) Now, the strange thing is, when I turn on my sound, while I wait for this loading screen to pass, I do hear the sounds of Windows booting up, skype booting up and msn booting up, and the occasional sounds of notices. Furthermore, when I insert my old gfxcard, a nVidia GeForce 9800GT, it boots up normally. However, I can not install any drivers anymore. Not from my old 9800GT CD, and not from the ATI CD that I got with my new 6870. I'm thinking about a complete HDD whipe, after ofcourse backing up important files on my external HDD. What to do guys?
