With limited kownledge, i really didn't find out the core casue of my windows 8 beta freezes at log-on except the safe mode. then I turned off the power and reset it, but then, upon attempting to log in, it froze during the "welcome, loading" screen that's displayed after entering ones password.

Booting it in safe mode works.

any computer talents can come up a fix for this windows 8 case? many thanks in advance.
