Almost a week I have this really annoying problem.
I use firefox and every time I'm trying to watch a video on youtube seconds later while the video is playing, the image freezes, the sound continuines to play for a second and then the cursor becomes bigger/smaller and there's an awkward sound like ''grrrrrrrrrrrrrrrrrrrrr''
I've searched the Internet for solution and I did everything.
I've reinstalled firefox and flash player, updated every single driver
, disabled the antivirus, cleaned the registry, cleaned the cookies and the history, checked the temperature (normal values), checked the event log but nothing.
Note: The day that I've noticed that crash on youtube I installed the latest graphics card driver and the Firefox 4.01 Beta.
