I have Acer laptop Aspire 5740 - 5780 with windows 7 Ultimate 32 bit. I am using Chrome. Windows is 1 year old, but it's not the first time this has happened.

Windows freezes whenever I am watching videos on facebook/youtube or when using SopCast. I thought there was some faulty plugin, so I recently re-installed chrome but it happened again. No keys work, and the sound of whatever I am listening starts repeating like grrrr..drrrr. Its seems like the sound in very slow motion. One time I left it in this freeze state for 5 min and it recovered automatically. It usually does not happen when I am using windows media player. I had some codecs installed but I removed them to see if that fixes. So far, I have narrowed it down to youtube/footytube videos and sopcast.

I have checked event logs but nothing special. Is there any way I can narrow down the problem or any suggestions on how to fix it.

I'd like to add that it does not always happen. Sometimes windows goes days/weeks without freezing, and sometimes it take a min into video to freeze.
