I spend a lot of my time at sites for watching online videos: youtube, gorillavid, thedailyshow.com etc. I used to watch the videos in full screen mode, and then that became very laggy. So, I started watching them with full-browser zooming. Then that became laggy. Recently, I've had to actually zoom out; otherwise, the video will lag so much that my PC locks. Could this be a symptom of my processor, RAM, or motherboard going bad? Has it, perhaps, anything to do with softwares like Chrome or the playeres the sites are using being updated?
