I've had 2 crashes now. Problem stopped after restart on both occasions. The laptop basically froze so even task manager wouldn't come up, and the cursor wrong move. Device doesn't recognize word mouse when I plug one in during this state.
Tonight it started slowing down, but I was able to turn off Wi-Fi and bring up task manager when I noticed the memory usage at 99%, and Feeds / Search Application being the main resource hog.
