I have an old (2013) Series 5 Ultra, made by Samsung.

Sometimes, shortly after or shortly before login it crashes. Seldom has this happened at other times. The screen is transformed into this:



I have tried lowering the resolution without any luck.

I have Bhodi Linux installed in it. Here is the result of lscpu

These are the results from hwinfo: https://pastebin.ubuntu.com/p/5YKBgdWWJm/

Now, obviously this is obscure and stupid and I could even live with it. But If anyone had some tips on where I could start looking I would be very grateful. I am techniful but I don't know where to start with this.

And since I had never used lscpu, another question: should I be worried about the vulnerabilities listed?

Thanks!

Run CDI to check HD health:

You could also run memtest overnight at some point to check the RAM: http://memtest.org/

Memtest, sure, I will. The other one, tho, looks like a ede, not sure that will work in Linux?
