I purchased a new hard-drive, and after doing a fresh install of Vista and installing all updates/latest drivers, I'm noticing that all of a sudden and shortly after being powered on, I get black boxes/rectangles all over my screen (below). Any ideas as to what could be causing this? On a (maybe) related note, my brand new hard-drive is squeaking. Not often, but it is there. Debating on whether or not it is worth the hassle of sending it back, or if this is related to the mysterious rectangles.
