Computer crashes when gaming

I recently switched some hardware in my PC (Motherboard and processor) and since then, whenever I play a demanding game the computer crashes- the screen goes black and the fans die down, HOWEVER, the computer is still on and short of removing the plug the computer wont turn off.

Event viewer shows the 3 Warnings. Two simultaneously, and one a few seconds later, all dealing with distributed COM error 10016.

The first:
The application-specific permission settings do not grant Local Launch permission for the COM Server application with CLSID
Windows.SecurityCenter.SecurityAppBroker
and APPID
Unavailable
to the user NT AUTHORITY\SYSTEM SID (S-1-5-18) from address LocalHost (Using LRPC) running in the application container Unavailable SID (Unavailable). This security permission can be modified using the Component Services administrative tool.

The second:
The application-specific permission settings do not grant Local Launch permission for the COM Server application with CLSID
Windows.SecurityCenter.WscBrokerManager
and APPID
Unavailable
to the user NT AUTHORITY\SYSTEM SID (S-1-5-18) from address LocalHost (Using LRPC) running in the application container Unavailable SID (Unavailable). This security permission can be modified using the Component Services administrative tool.

The third:
The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID
{2593F8B9-4EAF-457C-B68A-50F6B8EA6B54}
and APPID
{15C20B67-12E7-4BB6-92BB-7AFF07997402}
to the user DESKTOP-AG7BH3D\Yehonatan SID (S-1-5-21-3395407268-3618666329-165447070-1001) from address LocalHost (Using LRPC) running in the application container Unavailable SID (Unavailable). This security permission can be modified using the Component Services administrative tool.

I tried stress testing but no luck, also, I can't find any of the APPIDs in component service.

Thank you

Those Events are not relevent or significant. It is difficult using the Event Viewer to analyse a problem.

I would check your temperatures when running something demanding. Not a stress test as such, something more realistic.
Remove any overclocks on CPU, Graphics Card and RAM modules, check again.

Temperature never rises over 70, unless there is some problem with the monitor itself
I also don't overclock and I think my cooling should be enough (All fans working) is this a common symptom of overheating?

what temps are you monitoring exactly? you should fill out your specs so we can see what we're working with when it comes to helping diagnose this problem.

it sounds like your CPU is overheating and it's shutting down the PC but I could be wrong.

" whenever I play a demanding game the computer crashes- the screen goes black and the fans die down, HOWEVER, the computer is still on and short of removing the plug the computer wont turn off."

Often that is a sign of overheating somewhere, but it could also be a PSU not supplying sufficient power at peak demand.
Either or both could cause the shutting down.

Need more details on that temperature check.
e.g. This is an example, the Heaven benchmark on my Laptop. CPUID is used to monitor as it works well on the particular Laptop hardware.

I used radeons built-in software to monitor temps as well as speedfan 4.52.

My specs are the following:
CPU: Ryzen 5 2600
GPU: RX 580
Ram: 16 GB
PSU: Zumax pro 550W

The screenshot you posted is not sufficient to determine if temps are good.

For example, obviously there is no CPU temperature, and GPU fans according to image are not working at all, which may cause GPU to peek 100C+ and force restart to prevent physical damage.

This is a screenshot while playing.

I still can't see CPU temps.

Please download HWMonitor, install, run as Admin:
HWMONITOR | Softwares | CPUID

play game not too long to prevent shutdown,
minimize game, take screenshots of all hardware and post them.
