I have been trying to get Win7 RC1 working for the past day or so, using the upgrade method. Installation was fine, pretty quick, I started in Safe Mode, installed all the shiny new Windows 7 drivers, restarted, logged in.. and I'm greeted by a black screen with only my mouse, and Windows 7 Evaluation Copy. Build 7100 on the bottom right, in white letters. I can open the task manager, and run some software with it, but nothing really works as it should. Explorer.exe crashes upon startup, when I run explorer.exe, WerFault.exe also starts, which is apparently an error reporting thing, then explorer.exe closes. I don't even see the taskbar or anything. I searched around, and apparently the fact that my monitor has an HDMI input may be the problem, but I can't open Catalyst Control Center to do whatever fixes were recommended. Another suggestion was to disconnect my monitor, and restart, which did nothing. I disabled my graphics driver, and all that did was turn the black background to a blue background. Should I just give in and try a fresh install? I tried to repair the OS, but no problems were found. Does Win7 have problems with Shuttles? All that's running in the task manager: csrss.exe dinotify.exe (Windows Device Installation) dwm.exe (Desktop Window Manager) rndll32.exe (Windows host process (Rundll32) taskhost.exe (Host Process for Windows Tasks) taskmgr.exe (Windows Task Manager) winlogon.exe Really confused atm, I don't know how I can backup all my files when I don't really have access to anything, so a reformat is pretty much not an option. Help?
