[jimi23]

My pc:
8700K stock
2x8GB DDR4 GSKILL 3000mhz ( XMP
Corsair 750 i
Asus Z370 Pro Gaming.

I have 2 disks. SSD Crucial 525 GB MX 300 and Toshiba 500GB.
I have an question about system Windows 10.
I installed from Pendrive USB Windows 10 from here:
https://www.microsoft.com/en-us/software-download/windows10

On a fresh formatted ssd i install Windows 10.
When i installed Windows 10 there was a problem with...

 

1.When i go to windows settings, no matter what i click on system settings it wont opened. SO click and nothing.

 

2.Problem with web browsers ( Firefox and Chrome ).
When i go to some site, and try to download something ( right click save ), browser just hang,and not respond. I had to click X on the browser.

This happens in BOTH Firefox and Chrome, which is why I think it's an issue on Windows' part?

 

That was this 2 problems after i installed Windows 10 from Pendrive.
I dont know how but after 2-3 restart now its all fine and working fine.
I just ask why that happened? It maybe was related to my rams?
But i tested memtests and no errors. Thanks for suggestions.

I also checked DISK status, and GOOD HEALTHS.
