I upgraded from Vista 64bit to Win 7 64bit Home Pre. It was a fresh install no problems whatsoever. So I loaded the correct graphic drivers, I have the ATI Radeon 5870 I made sure to get the correct 64bit driver package. Installed it with no problems restarted and I get a black screen. My monitor says out of range like it doesnt recognize my monitor. You can hear windows boot up as well to top it off. I played around with my monitor I have it hooked up via HDMI and had no success. Im stuck any suggestions. Thanks.
