Slow during import

Hello this is my first time posting, and have been having this issue for many months and now I have pulled out enough hair that I need help in resolving this software freezing and slowing way down where I can't do anything either in lightroom or out of lightroom. 

Recently I have had to log out of lightroom and log back in to get it to work again. I have had a heavy flow of images (thousands that have been imported) that has seemed to be some part of the issue with the software running slow or freezing. I have even had to restart my computer several time. 

I have asked my husband, who is more computer savy that I am (by miles) and he says that I have all the recommended system requirements to run the software. We check the task manager to see if anything is being bottlenecked during a time when the program decides to freeze or become extrememly delayed in the speed of the action its doing.

I honestly don't know what to look for and I am do not know how to work the back-end of lightroom as in all the backup catalogs and where they go or what they are for. Please don't scold me on that, I have used the program for editing and I have been teaching myself how to work this program since I started using it.

Now if you have read this far....I desperately need advice, do I need new parts to my computer to run the program better, is my computer being slowed down due to other programs running in the background that I am not aware of. Any advice would be so helpful.....and if you could explain in detail or "dumbing it down" for me since I really am not knowledgeable with the tecnical part of computers.

Thank you so much for your help!
