Computer wakes up with fan roaring

My computer is about 2.5 years old, the video card is a bit over 1.25 years old, I think.

 

It works great in general, and has, except when the old video card went out.

 

I leave it on all the time...it is set to sleep after 2 hours.  Each night, it sleeps, and wakes up in the morning just fine.

 

EXCEPT: Now, about 2 times in the past two weeks, and several times in the past month or so, it doesn't wake up.  Instead, when I hit a key on the keyboard, a fan inside starts "roaring" fast, like a jet engine.  Normally, the computer is totally quiet while using it (at least I can't hear it sitting under my desk about a foot away from me).  I work it pretty hard and never have had any overheating problem.  

 

When the problem occurs, I have to hard boot it.  And sometimes, it just does the same thing a few times.  What "seems to help" is turning off all external USB drives (I have two self powered USB3 external JBOD drive boxes each with two drives in it.)

 

So I turn those off, and then after a try or two, the computer comes on without the fan blaring (and as I mentioned, when the fan is blaring, it doesn't actually boot).

 

I am wondering if anyone has any idea what this could be?  The video card (I note there's nothing on the video displays at all when it doesn't boot)?  The main power supply?  The motherboard?

 

I depend on this computer for work, so I'm tempted to replace it, since I usually buy a new one after 2-3 years, but this one's "loaded" and still seems to be quick enough so it seems a waste to replace it.

Try reseating the RAM. I've run into this problem a few times at work where the computer won't start but the PSU fan will kick into overdrive and go nuts. Take the ram out and blow out the slots with canned air and blow off the ram as well. This may fix the problem.

It happened again Tuesday morning when I tried to wake it up.  It was fine then for about a week of being on all the time.  I had used it last Monday night at about 1am.  So this is about 6 hours after it "went to sleep" (again, I don't shut it down at night...it is set to suspend after a period of no use).  Here it s:  https://youtu.be/_e_SoCnpXOQ

 

Note that the clicking you hear throughout that sounds like typing is actually the focus motor on the Canon S100 which was used to shoot the video.  I just pressed a key on the keyboard to wake it up...typing doesn't help :)

Holy crap... sounds bad. I hate to make you do things over, but do you have any suspicions as to the fan it may be? It could be case, CPU, GPU or PSU. You replaced your graphics card you said? Is the GT 640 the new one?
