Itunes+Quicktime problems

[M16]

Hey everybody been awhile since I posted.

I have recently upgraded my computer and having problems with Itunes+Quicktime

Everytime I try to play something in Quicktime it plays for a couple seconds and then freezes, and then the whole computer freezes.
I have Quicktime Pro.

Some movies when I try to put them in Itunes it does the came thing.

I have reinstalled countless times with no progress.

I have searched and haven't found anything.

Ctrl+Alt+Del doesn't work


Ive tried reinstalling my video drivers which have not worked.


Any info/help you can give me will be highly appreciated.
