Internet is ruining the performance of the computer

[Neelke]

Forgot to tell you this. Since my family had borrowed a movie to watch, I joined them and my computer was in resting mode. When the movie was over (around 1 hour and 30 minutes later), I went back to the computer and started it again. Then suddenly it began working again. Had 5 browser windows up and the internet on, didn't lag at all. For some reason.

I'm gonna try later today if its still working still.
