Hey guys, I was wondering if I could get some advice from posters that have an aptitude for computers. I have a 2010 Macbook Pro laptop which has recently started to act up. Sometimes when I am watching a HD tennis highlight clip or match the video randomly starts seizing up. The graphics in the video become jerky and it is unbearable to continue watching the video. That is not the worst part. When the video starts slowing down, the entire computer starts acting up. The trackpad starts lagging with the video and navigation becomes a serious issue. Majority of the time the laptop is fine, but it randomly starts acting up in the manner I just described. Any thoughts on what the issue is?
