After like more than 5 times this thing happened occasionally, I thought to post this to ask you guys' experiences :)
I felt like this thing was closely related to Logging Off/Switching Users.

Okay, what happens is: when I switch user and log in as another user; and then switch user or log off and go back to my account, the screen goes blank :o this doesn't happen frequently, but occasionally. And also there is a white curser blinking in the far top left corner. The keyboard doesn't respond. No mouse point. The hard disk light flashes every 5 seconds like. Mmmm, what else? um I think those are what I noticed. I have left like 3 ~ 4 hours leaving like that to resume. But nothing happens. And it end by my finger hits the Reset button :angry: :(

I wonder if this thing happened to any of you guys? :unsure:
Any body know what is the core reason for this.....?

Funny you should bring this up , this has happened to me also ,I also get this on bootup . This seems to happen once a month ? any body have any ideas ??........ B)
