Basically, I installed windows 8 the day it came out and I installed the graphic drivers for windows 8 as soon as it finished installing from the website and it was fine. But when I restarted the computer, the windows logo screen would come up, but after loading the screen would just flicker every two seconds. I can't even see the windows login page. This is definitely a graphics driver problem because thankfully I switched back to my intergrated graphics and was able to run from there, but my ATI Radeon 5450 HD is not working at all... Any suggestions?
