I just recently build a computer for my friend and I'm currently running tests on it. Everything works fine until I install the video drivers. Yes, I'm install the latest from AMD (card is an HIS 6770). I have done cleansweeper several times and tried older drivers with no success. Everything else works fine. This is driving me nuts as this is the only obstacle. After restarting from installing the drivers, just sitting on the desktop or clicking a few windows, the screen flickers to different colors at different times. Sometimes Black with white. Or Aqua blue with lines. Sometimes, it stays black for a few seconds, then automatically reboots and gives me the option of safe mode booting. It works perfectly fine without any drivers for the video, but once i update it all these issues start to pop up. Anyone have an idea on what to do?
