Oh great. Last night I got random little rectangles coming and going on my browser screens (seems to have stopped today); the boot-up screen lost it's wall paper and no more prompt for 'learn more about this photo'; and McAfee doesn't launch as it usually does on boot-up (but the VPN apparently launches though I can't open it) -- it won't respond at all when clicking on the #McAfee button. I have bad feeling about this...
