Computer makng lots of noise when editing in Premier Elements

So, I finally limped thru the finish line and finished editing my video. If anybody wants to see it, I'll give the link. But, of course, don't feel compelled to look at it. My target audience is family and friends--and previous patients of mine.

But what I really want to say is that when Bob Peru said it was probably the processor rather than not enough RAM, I really thought he was wrong. Probably because my computer was pretty up to date--though not exactly considered a "gamers" computer when I bought it about 6-7 years ago. But the main reason I didn't think he was right was because if he was, that would mean--at least in my view---that  I would have to start with the expense and the time of getting a new computer, transferring, etc. But, alas, I think Bob was correct.

WHen I was able to run about a 4 second section of my video, I kept the Task manager up as well. And this was after I disabled my  virus and malware programs. So, just prior to hitting play, the CPU usage was at about 2%. About 2-3 seconds after hitting Play, the CPU usage went up to 100% And the memory (I assume that means RAM) went up to 87%. So, I guess when the CPU is at 100% capacity, that's why those fans are in emergency mode..

Perhaps this is not the site to ask about just getting a better processor for my computer. I am not someone who can build a computer---just in case you haven't guessed by now! But, if it were easy enough, which I tend to  doubt, perhaps I could just add another main processor or mother  board, or whatever it's called. I could always search on this, but if you have any good ideas, I'd appreciate hearing it. Of course, I had SO many layers on this video that it's possible my next one will not require as much processing.  It wasn't just the noise of the fans which concerned me, but I got lots of stuttering and other types of jamming when I would go thru the  video. I finally would just edit just a minute or two at a time, which might have helped somewhat.

Thanks again for your excellent support.

This is a Dell desktop. 

XPS 8930

Processor- Intel(R) Core(TM) i7-8700 CPU @ 3.20GHz  3.19 GHz

RAM 16.0 GB (15.8 GB usable)

Hard drives:

1)Samsung SSD 860 EVO 500 GB

2)2 TB hard drive

I really don't know what type of fan. I could look if you could tell me where to find it.

Re: the location of the fans, I looked at the bottom of the case, and there are no vents there. It looks like there an approx 2-3 " square on the back of the computer, near the top which looks like a vent to me.

Again, I don't really care if the fan is making noise. But, I've found it's difficult to edit when this is occurring, and frequently, as I have said, I can't even just go back a few measures and just listen to what I've already included in my video--bc when I try to play, there are  pauses, stuttering, or freezing. I seem to have to wait until the fan noise dies down after about 10-15 seconds.

Thanks for your interest.

Hi, 

I'll get to John Smith's reply a little later. But, as for the question from Bob Peru: No, I'm not sure it's not the fan making noise. In fact, it sounds like a fan. And, as I just saw 5 minutes ago, it's not just when I'm editing something. Even if I just listen to a few measures of the mix I'm working on , it immediatly start to make that loud fan-type noise. 

BUT, the reason I thought it might be the actual disk making noise-and I now realize I'm probably wrong--is that while this noise is going on, I usually can't do anything in the program. So, if I want to listen for 3 or 4 measure, and then I want to go back and listen to those exact same, the program seems to either not let me do it or seems very sluggish. It's not until the noise goes away that I can do anything. So, since it wasn't doing that in the earlier part of the video, I'm thinking that I'm overloading the disc or overheating it. Maybe it needs Gatorade?

I  should add, to be  fair, that when I just listen  to a few measures, the fan or fan-type noise only goes on for about 10-15 seconds. Still, since I"m often having to listen to a particular part mutiple times to, ie, make sure everything is synced exactly correctly, it adds a lot of time to this process if  I keep having to  pause all the time.

Thanks very much for your replies.
