OK so I have a laptop that has a Core 2 duo 2.2 ghz and Intel mobile chipset series 4 graphics. Very recently, my computer hasn't been running well, but I take very good care of it. The main problem is, when I watch a Youtube video, both of my cores are at 100% and the video goes down to around 5 fps or lower. Also, my computer has been shutting down randomly. A little help?
