I just purchased a new HDD today, fresh install of Windows 7 Ultimate 64bit. Starting to redownload and install everything from games, to drivers, to browser, etc. As far as I can tell so far this issue only arises when using Twitter and Imgur. For imgur specifically Google Chrome loads pictures at a choppy rate, a lot slower than usual; same with twitter. It seems that Chrome is freezing for a couple seconds and resuming, like a sort of lag. On twitter I experiences freezes when X'ing out of a tweet or DM window, loading DMs, clicking on pictures, sending DMs and tweets.
