Any hardware experts here? Serious problem in LM19.1 and LMDE3.
I am having a grave problem with both Linux Mint (19.1) and LMDE3 on the same computer.
Linux Mint 17.3 is no longer supported, so I installed LM 19.1 on my aging computer a couple of weeks ago (Core i5-3450, Gigabyte GA-H77-D3H mobo, 8 GB DDR3-RAM, 500 GB HD, 500 GB SSD, Geforce GT 630).
Since about 2012 (that long) Linux Mint has run fine on this PC, alongside Windows Vista (yes, THAT Windows Vista). LM 17.3 and Vista were in dual boot on a 500 GB HD. Linux Mint 19.1 was installed on a newly bought SSD (Crucial MX500) and everything was working well (with Mint 19.1, at least).
Then "weird" things started to happen with Mint 19.1.
After a random amount of time watching YouTube in Firefox, Firefox would crash/hang. And a number of seconds later, the WHOLE of Mint would "hang"...
Only the mouse cursor and the keyboard lights would still work - nothing else - and I would have to do a hard reset (long live the reset button...).
A number of days ago, for example, the PC spontaneously rebooted, while watching YouTube.
It only seems to happen, while watching YouTube videos. I am now posting this, and the PC works just fine, with fans humming along nicely.

I have been replacing as many hardware parts as possible:
It is not the PSU (from an old OCZ 600W to a Corsair RM650X).
It is not the mechanical hard drive (it happens with the SSD too).
It is not Firefox (the "crashing"/"hanging" happens with Opera too).
It is not the (old) Geforce GT 630 (it happens with a new (second-hand) GTX 770 too). I have a Geforce GT 1030 (by MSI), but the PC will not boot with this card and stays stuck at the Gigabyte BIOS/UEFI boot screen (odd...).
It is NOT Linux Mint 19.1, as I first thought, because the previous weekend (3 days ago) I have installed LMDE3 "over" LM 17.3 on the mechanical harddrive (LM 19.1 is on the SSD). And since last Saturday, with Chromium [73.0.3683.75 (Developer Build)] in LMDE3, the tab in which YouTube was open, crashed once (although Chromium did not crash/hang).
And last night after over 45 minutes at YouTube in Chromium, my 24-inch Samsung LCD went black, and that was it... The PC was still powered on, fans running and such, but no image... I powered down the PC by holding the POWER button and left it at that, last night.
I am now typing this in LMDE3 on said computer, and everything works just fine, knock on wood.
I have inspected the motherboard (GA-H77-D3H from Gigabyte), but I see nothing suspicious (like bulged or leaking capacitors or whatnot). Same with the Geforce GT 630, which was in this PC since I bought the PC.
I have not checked or tested the RAM yet (1 x 4 GB and 2 x 2 GB; little mistake in buying more RAM, but the 8 GB is seen and works fine (also in Windows Vista, which shows a BSoD for now, but that is not the problem--well, it is, but never mind that here and now ).
Since this is an aging machine, I am slowly starting to fear that this is a hardware issue and that it may be the beginning of the end of my loyal computer, lovingly called "Puma".
(There's also the "Cougar" (with an i5-2500K, about as old or even a bit older as the aforementioned "Puma"), and there's the "Panther" (with an i7-3770K), and then my 4 months old machine called "Ryzen", by lack of imagination, with a - you guessed it - Ryzen 5 1600.) Yes, I have a few computers.
Anyway, the "uptime" of LMDE3 on the 500 GB harddrive is now over an hour and 20 minutes, and it is running just fine. No "hanging" of Chromium or of LMDE3.
This grave problem of "hanging"/"crashing" only seems to happen during YouTube video's.

So hence my questions, Are there any computer hardware experts here who might have an idea about what is going on?
Is there a way to check in Linux Mint (19.1 or LMDE3), like in log files, what exactly happens during a "crash"/"hanging" of Linux Mint/in LMDE3?
