While playing some games my computer will sometimes freeze, the screen will go mostly black, and then the computer will power off and restart. It doesn't happen in every game and the only thing I can say that connects the times it happens is that I can hear the fans going very hard. Maybe it's a power supply issue? Are there any diagnostics software that will record what's going on and save it so I can look at it after the computer crashes?

The CPU hits 100.0C when doing the actions that typically cause the crash, that must be it. Is there a way to help mitigate the heat issue?

Here are the saved stats so you can see everything. It doesn't seem to have saved the max temps but when I was testing:
Core #0 95
Core #1 98
Core #2 100
Core #3 100
Core #4 98
Core #5 97
Core #6 95
Core #7 92

Package was at 100

Although your CPU can function at that temp, it's probably 15°C too high. First step is to clean out your unit. If no good, remove CPU, clean up and reapply thermal paste.
