today, out of nowhere, this buffer like symbol appeared in the top right corner of my screen. ever since, higher end games (bf4, farcry3,crysis 3, etc) have been very choppy and un-playable. what in the world does this symbol mean? i just installed a corsair h100i liquid cooler and it started happening, though i very much doubt that has anything to do with it. i was wearing esd protection so i doubt i fried something.
