100% Disk Usage

Hello everyone.

I recently bought a new ASUS X441U laptop with the following specs:

- Core i5 7th gen (2.5 GHz)
- 4 GB RAM
- 1TB HDD
- Nvidia Geforce 920MX

It has really good specs but I've been having problems with the HDD since every program, every action I make on the laptop takes 100% usage and makes it run very slow. Everytime I close or open Firefox, I check the task manager and it goes straight up to 100% and so on with every app I have installed at the moment.

Even pressing the windows key on the keyboard takes it's time to open.

I tried to disable superfetch, prefetch and windows search but nothing has worked so far, there is always something that takes the usage up to the max.

Is it normal? Shouldn't be always the usage between 20% and 40%?

 
Solution
Considering you only have 4 Gb of RAM, which is low nowadays, I suppose high disk usage is caused by the system using pagefile extensively to cover low RAM amount.
