I have vision problems, and the content of what you pasted doesn't contain all of the information that is needed.
I do see that CPU temperatures are very high in the beginning, but not so high in the end. This could mean that the system is overheating (which can cause shutdowns and BSOD's)

I assume that we are having language problems. Unfortunately, I do not speak any other language.
What may I do to make this easier for you to understand?
