I have been trying to get Windows 7 RC1 up and running on my my rig but have been met with a black screen the very first time the system attempts to boot into windows, but before the setup is officially complete (meaning i can't get into safe mode at all). I have installed onto a clean hard drive. I have a Q9550, 9800gtx+ and 8bg of ddr2. I have been able to run build 7000 of windows 7. I have already tried installing with only my mouse, keyboard and 1 monitor attached to the computer (the only "solution" i have come across so far) - no success. Btw, the black screen is all black - no watermark, no nothing. I have also let the system sit for over 8 hours on the black screen and tried installing/booting with just 1 RAM module.
