In the beginning, I had a NVIDIA 9600GT graphics card, and Windows 8 was smoothly running on it. Then, I bought a GTX 650 Ti, and inserted it into my computer instead of the 9600gt. When I booted up Windows, it turned out to be in a low resolution mode, and the screen had some serious vertical tearing (5mm vertical stripes). I tried to boot it into safe mode and reinstall the drivers, but to no avail: 1-2 times the screen was normal, but after a reboot it reverted to the f-ed up state, or even worse, I got a black screen after the windows logo. The drivers I used were 306 and 310 WHQL.
At the end, I installed Windows 7, just to check if it was a hardware problem, and luckily it isn't - the computer works flawlessly. Except that I got used to Win8, and I want it back.
Can you help me to somehow install Windows 8, and use my new gpu at the same time?
