Hi, upon checking and analyzing the event logs you have, there is a significant error with Kernel-Power, which means there is an error with the hardware itself, this might happen when the processor is overheating or getting low power from the motherboard or in the power supply since you have swapped the hardware and still having an issue, I suggest contacting a local technician to physically check the device for any hardware-related issues, moreover, before doing that, let us make sure that there are no software-related issues on the PC, I suggest doing an in-place upgrade wherein it will upgrade the device to the latest version and repair all issues without deleting any files.
