I often watch streams on twitch.tv or azubu.tv at 720p quality. Recently it has started lagging really bad (as in un-watchable).

I know that it has to be an issue with my computer because I can watch said stream on my tablet perfectly, and even on my brother's old laptop without any problems so it isn't my internet either.

I don't have any issues browsing online. Its solely a streaming issue (even YouTube has problems) with videos not loading properly.

My computer is <1 year old with 8GB RAM and i5-3570K CPU. It shouldn't have these problems.

The only thing I can think of that might be causing the issue is maybe my wireless card? Or maybe there is a bit of dust inside my computer and I should vacuum it out? Does anyone have any ideas or can suggest something to help me fix it? Would be much appreciated.
