My brother bought an MSI Classic CX623. It was working fine in the beginning, but now it wont play videos on youtube with internet explorer. The sound is there, but no video.
If I run google chrome, the videos play on youtube, but the slider at the bottom of the screen that shows video progress, is not visible. That entire area is just a black stripe.
I've tried reinstalling flash player, but to no vail. According to my brother, the youtube video error took place after installing Windows Live Essentials 2011. Tried uninstalling it, but it didn't help either.
