I've had issues with my CPU before, but this is about another subject. I experience my CPU usage and temperature going up and down while doing the same thing. I am streaming videos on the internet, nothing else. But the CPU goes up and down, up and down causing spikes in the video which tend to get really annoying. I have a laptop, Lenovo G510. I can play games like Counter Strike fine without this change of CPU, as long as it is cooled. Why should streaming a video be worse than playing a game online?
