2 things, Event viewer always has errors, they may not be the cause of your problem; and Event 41 is a reaction to the shutdown, its not the cause. Windows runs a report at startup to check if PC was shutdown right the previous time and eill create an Event 41 if it finds it wasn't.
I could find a fix for that error but it refers to Win 7 and the steps don't match Win 10 after a certain point.
What are the specs of the PC?
Freezes aren't usually windows, they normally hardware so might want to run the free version of http://www.memtest86.com/ on your ram, one stick at a time. It creates a bootable USB so don't need windows. Any errors are too many, stick needs to be replaced.
