Have been having errors with PC for last 6 - 10 Months

Which fans run at full speed when the problem occurs? Only GPU fans, only CPU fans, or all of them, incl. case fans (if any)?

When the system appears dead, try to access it remotely to see if it gives out any signs of life (ping, shared files, remote desktop - something you've tested while the PC was running fine).

I'm willing to bet it's all down to Windows. Get an SSD and do a fresh install, chances are even if the OS check doesn't throw any errors that something can be borked bad there.

My 2c anyway.

Nearly every instance I can find of these errors is caused by third-party software (the exceptions being on server OS and not germaine to your situation). So, what all do you have installed? Especially games.

What are the critical errors that it has logged (i see it has a couple)? Those are the crashes. These "Kernel-Event Tracing" errors may be a symptom but are unlikely the cause, they are related to ETW. Can diagnose them using logman and perfview. Could be as simple as restarting WMI, but in any case, I don't think that is our main issue here.

download bluescreenview and let's see what it logs when the system actually crashes. See if we can find an offending application.

I would start from scratch with windows. Install nothing but drivers. Then start loading software one at a time and see at what point it starts crashing. There will be your culprit.

This is all assuming that it is not a hardware issue. Definitely do take a look at power supply voltages and hard drive health to be sure. If the same thing is happening with two different sets of ram, it's probably not that.
