direct links of old sources may well be a few messages off.

Uhm, that explicitly says:
 [Hardware Error]: ... Machine check Exception ... 4 Bank 0 ...

Which means, well, that your hardware is broken.
Specifically, you likely have bad RAM.

Depending on what exactly this is about,
you may even be able to "fix" this
by changing some BIOS settings.

Try google for the rest of the messages in that screenshot.
