No audio, no moving imagery and a bare minimum of functionality

The last two days my internet performed poorly, but it worked (in between crashes). Now it took me 12 computer restarts and hours of patience to get to this page and plead for any sort of internet. I can't visit any page with moving imagery or it will crash, it won't start any video if there would be sound on it, stating that I don't have permission or simply not doing anything at all. I can't even finish the news-program I was watching on public acces tv. Please fix this!!! I'm desperate! I need to watch instructions for school and see my work-roster and I can not acces any of those pages anymore.
