There is something not right here
On post 12 Zbook said
Uninstall: cfosspeed6.sys
and then on post 24 I said
uninstall cFosSpeed 11.07
So I am puzzled as to how you uninstall
cfosspeed6.sys
and then on your log of the 12 Feb have
cFosSpeed 11.07
either you are reinstalling it OR some software you are using is automatically installing it.
It is still shown as installed on the log of the 16 February
and it is a running service
cFosSpeedS cFosSpeed System Service Running 5144 Automatic
YOU need to uninstall it
cFosSpeed - Faster Internet access with Traffic Shaping - cFos Software
There are numerous reports of it causing problems and as you say
=========================================================================
The other issue that concerns me is your hosts file
see attached notepad file
Not that those links have been blocked, or the length of it, although that is not good, but the fact that if you are using such indicated links, there is no really effective way of evaluating what has been downloaded to your system
You can be assured that downloading from such as the Pirate bay etc and other such sites - on torrented downloads is a sure fire way to acquire unwanted software
I am not qualified to examine your system for malware.
You can run scans with Malwarebytes and many others, but it does not mean it will find everything
=====================================================
I suggest you start with the uninstall of that internet booster
====================================================
Then test the system and if it still crashes.
================================================
I cannot determine if you ever tried the system for any length of time, as I suggested earlier, with two sticks of ram - it will run perfectly with 16GB
If not you should so so IF it crashes after uninstalling that internet booster.
DO NOT make more than one change at a time and test it for two or three days AFTER each change OR of course until it crashes. Otherwise we will never determine the cause.
I have re- examined your hosts file IF the system still crashes after the uninstall of the cfosspeed and the ram test
RESET your hosts file as here
Reset Hosts file back to default in Windows
