Flash video freezes in Windows 7

Hello,

I for the life of me cannot figure out what the problem is. I have the same issue (video freezing when watching flash videos ie. youtube, VEVO etc...)I have updated my flash software as well as the driver for the video card and even tried another video card in my system. I find this very strange because it only seems to happen with Flash and no other video file format. Any help would much be appreciated as I have been struggling to have this problem fixed for months now.

Thanks
