Re: Toshiba Satellite A215 making annoying noise
Use a can of air to clean the fans - see if that fixes the noise.
Streaming videos requires a certain bandwidth to stream consistently. So when you download videos, movies, music what is the kb/s that it downloads? My guess is you don't have very fast internet connection speed so you can download stuff fine (slow but fine) and you can't watch streaming videos because it requires a minimum bandwidth to keep up with the video (pausing the movie will allow the download to get ahead of what is being played).
Google speakeasy speed test, run a few of those and let us know your bandwidth speeds.
