It's actually not my computer I recently found out, it's my internet service because it uses Java. When I use public wi-fi, there's no problem. A bit irritating. This happens with certain forum software. It's bizarre. Still though, the site owner should disable video/flash based ads on adsense. Those actually do slow a lot of computers down, and the CTR typically sucks on them anyway. A forum like this would produce better income if they showed only text-based and image based display ads only -- no fucking video ads. My 2 cents.
