Laptop gets impossibly unresponsive in afternoon

In the mornings when the laptop is first switched on, everything works fine. But by the end of the working day the laptop is unbearably unresponsive. For example, when typing into MSWord in the morning, it works perfectly. But by the end of the day, when typing into MSWord, I do not see the text appear in MSWord until after about 10 seconds at a time after typing it. So if I am touch typing, I see blocks of words appearing in MSWord every 10 seconds or so.

This seems to happen for all apps on the laptop, not just in MSWord. The above issue happens no matter how many apps I have open at the time, so even if I just have MSWord open, it will still happen.

Laptop specs:

CPU: 4 Core i7-8650U (8th Gen)
RAM: 16GB
SSD: 256GB
OS : Win10Ent64

I have tried looking at the task manager, I can't see anything which might be using 100% of the CPU. I have also removed any unused startup apps to see if that makes any difference but it does not. The only thing I have found which temporarily fixes the problem is a full restart of the OS.

I have also updated the OS to it's current latest (non insider preview) and have all the latest manufacturer drivers, bios updates, and firmware updates installed.

So my question is, how do I go about figuring out the cause of this issue?
