when you acess the category you just get a white screen. i've seen that on a few categories today.
same for some user, if i click on their "points" tab etc.
that has nothing to do with your windows or overclock. it's a common problem which pcmark04 and dual\quad etc. cores.
the solution

it's ok. pentium m's/celeron m's can be used on s478 with an adapter as well (ct-479).
the category just say both names so people know the celeron is pentium m based.
