I'm having a terrible time with my ultimate Vista machine. It boots up and after a black screen appears for about 6 minutes finally the logon screen appears. I see the icons for both of the user accounts but when I click on them, nothing happens it does not allow me to enter a password. You can tell in the background its doing stuff. I've let it sit this way for a day.
I've also booted into safemode with the same event, except I get the logon.scr application failed to initialize properly, and then the screen goes black.
I've booted to the Vista cd, and ran a repair which told me I need to disconnect any camera or music devics (everything is disconnected)
I also restored to a very early point- still same problem
I've run memory diagnostic- still same problem- memory is ok.
I can't get into my machine! I really need help getting passed this.
You can try a repair install (NOT the Windows startup repair... an actual reinstall of Vista)... you'll have to Google Vista repair install to get instructions, as I don't remember how to do it off the top of my head.
If that doesn't work, then a reload is in order. Backing up your data will be problematic if you don't have access to another computer.
