Another fucking support thread

I've been having this problem: pictures in web pages don't appear where they are meant to go, and sometimes don't appear at all. Sometimes a picture will appear instead of the page, and i have to refresh a couple times before seeing actual html, and so on.

At first i thought firefox was going insane because of extension issues fucking up the cache or something to that effect, but internet explorer is giving me the same crap. Any ideas?
