Windows 10: Windows 10 gets slow or freezes when left idle

Hi all i'm new to this (old account but didn't post that much) forum and i have a problem with my desktop pc

So i have Windows 10 Insider Preview (14986) and yes i know that windows insider builds have problems and shouldn't be installed as a standard operating system but i can't go back i have too much stuff installed.

And now let's go to my problem : Every time when i leave the computer and do nothing on it when i come back the mouse lags and the user interface freezes also opening the explorer takes a little bit long & opening folders makes my Computer freeze sometimes. The other problem is the Computer also freezes in games and i know that it is the Computer who freezes and not the games (Dark Souls 3 & Call of Duty: Infinite Warfare) and i have to close them with the task manager then. The games itself run perfect i have a strong GPU.

What i already did :

sfc /scannow and DISM both are showing no errors.

So does somebody know a fix for this ? Or does somebody have the same problems with the 14986 Insider Build ?

Thanks for the future help and sorry for my bad english it's not my native language. *Smile

I forgot to add that my Event Viewer shows 3 errors which don't stop (Perflib, PerfNet, ESENT) i have attached 3 photos to the errors.

Edit : Dark Souls 3 freeze'd again and i could get an error report with the program WhatIsHang i will attach the txt file.

pc freezes when left idle

The pc freezes when left idle. Even the mouse wouldn't move. Looked at event viewer, nothing looks abnormal in it. It's definitely not hard drive because I recently replaced it with a new one. Does anyone have a solution to this?

 

I would update your network interface drivers and your motherboard chipset drivers as well.
