So when i try to login to win 7 64 all i get is the loading screen (4 little partials) then a black screen with the cursor. i can move the mouse around and that is about it. ctl-alt-del doesnt do anything, neither does any of the other windows modes. they all load to that same black screen. i tried putting the win7 disk in and having it repair startup problems and it couldnt find any problems. i ran chkdsk r, and that turned out fine. anyone else have this problem? and if so what did you do to fix it?
