Out of the blue today the fans on my dell started revving nonstop, and I mean multiple revs per second. All of my temps are normal, and there is no excess system resource usage to speak of. I don't think it's fan failure since it sounds like both fans are doing it. Not only is it concerning...

Screen lights up at power up. After various amounts of time (a few seconds once, but mostly a minute or so) it beeps 2 times. I've reseated memory and tried it with different sticks. No change. Disconnected the CMOS battery......and plugged it back in. No change
