video folder freezes.

Oh my... what's wrong?
Im having this problem, sudently, every time I open a folder that contains
videos, the PC freezes, I don't even click any of the files...'
could someone help me please.

the only change I have done is that I suposedly installed a mp4 Codec.
oh, and the sistem restore just wont work,
it does everything but the it says it could't restore,
and the option is enabled.

Fixed.
Yeah, back to normal.
I figured that may be, as before with other apps.
a re-install would fix it; a re- install of what,
well, Windows Media Player,
and it did.
