I have more than enough free RAM memory at every time any of the problems occurs.
Virus/Malware scan do not help a lot, I even tried reinstalling the OS, without any luck.
In advance, thanks for looking into my problem.
For at least 6 months now, PC has been experiencing RAM issues, for example chrome would throw me "out of memory" messages or certain software would not even freeze but just "exist" and be unresponsive until I can turn it off in the task manager...
