Okay , So while venturing thought the internet I have found that OBS in itself cannot make the system collapse no matter what , drivers however , can freeze the system , since OBS communicates with
Video and
Audio drivers , the issue might be solved by replacing the drivers with ones which are recommended by the OEM.
The Nvidia drivers is an exclusion to this rule as it is always updated , the ones that apply are intel driver and Realtek HD Audio driver.
When I first installed Windows 10 , I let it install The Intel and The Realtek Audio driver , later on I replaced them with other versions for other purposes but it didn't work anyway , I thought maybe that versions could be the cause of the issue , so I decided to uninstall them and let Windows do it's job.
Windows Installed The Intel Driver via Update but for some reason it didn't install the Realtek driver , so I reinstalled the one that I have just removed as it is the only thing that I got now , at that moment , a very strange thing happened , I was supposed to restart to complete the installation of Realtek Audio Driver , but I delayed till Handbrake ( A Video Encoder ) Finishes encoding the video that exists in the post above this , I was using QSV as the encoder , suddenly during the encode , the system froze , just like it does with OBS , but for the first time OBS wasn't running , I then suspected that the problem is with QSV as this is the only thing in common between OBS and Handbrake .
After that I hard reset the system and encoded 5 videos in a raw with Handbrake QSV , it didn't freeze , I recorded with OBS for hours with no freezes at all for the first time , I don't know how but it looks like problem solved ! , I will update here incase it froze again.
TL;DR = it was fixed by letting Windows install all drivers but Nvidia Via Windows Update .
P.S = it wasn't low spec issue as
@SoWhoYou &
@Unknown Richard speculated , please think for a minute before bashing nonsense into someone's post , I have clarified at the very first post that there were no lags or other issues than the random freeze , which means the specs is doing well , low specs lag while recording not stay at 60 FPS then crash the OS -.-
