When ever i am watching a YouTube video in 720p or 1080p there is a random stutter or freezing for 1 second or so and it happens about every 3-4 seconds it does this with chrome and Firefox. but if i watch the video in 480p its fine. and i am not sure whats going on it all starting last month or so. and on some videos the audio goes out of sync by up to 5 seconds its all very annoying.
