Windows 10: How can I fix a very slow computer with 100% disk usage on the task manager?

Randomly my computer will become very slow. When I open the task manage it shows 100% disk usage and is stuck there. Sometimes after running Super Antispyware it will get better but that can take hours and may need to be run several times. It doesn't find any problems just running it helps.

Windows 10 100% disk usage in Task Manager


Hi,
i have dell inspiron 15 , 5000 series , OS is windows 10 64 bit.


Recently i had a problem at the laptop:
Disk utilization is quite constant at 100% even though no program runs parallel and there is no traffic between the hard disk and the external device.
I searched in Google for solutions and found this issue quite common in Windows 10. I tried all the options from the solutions offered in the links but without any success :
1. Windows 10 100% disk usage in Task Manager [SOLVED] - Driver Easy
2. How to Fix: 100% Disk Usage on Windows 10 Task Manager


I also tried to run a disk repair on Windows 10 and even "Reset to default" of the windows which means getting clean operating system - deleting all the files that I had and that did not help either.
Still after booting the computer and during work the disk utilization is 100% fand the computer is very very slow.
Do you have a solution?
Is the hard disk malformed and is this what causes windows to show 100% disk utilization ?
