Windows 7: Sudden Reboot (Win7 64bit) after Installation Complete & Black Screen

03 Jun 2011   #1

Windows 7 Ultimate 64 bit
Sudden Reboot (Win7 64bit) after Installation Complete & Black Screen

I have problems entering windows after the first installation of Windows 7 64 bit built 7000.
After seconds the welcome (splash) screen appears, the windows suddenly reboot automaticaly.
After that, black screen appears with dashes blinking.
(Actually, my current OS is Windows 7 32 bit built 7600, but I think it isn't cause of the problems. I have formatted the local drive, in which my current OS was installed, before I install Win 7 64 bit).

So, somebody, help me please !

Why are you trying to install a very old beta build of Win7? How would you activate it?
