Im still on the search and found out that when working on a new user account, that has no apps that are used on the account that the issue happens, seems to be working flawlesly... well till now that is.
So i only think that it might be an app thats causing this... maybe working in the background, i dunno.
So i was thinking... might there be a way to find perhaps some log, that defines the reason why the freeze happens?
What can i look for?
btw... the only app thats working when the issue happens is Chrome :-(
