30 minute crash

[Linux_Mint_User]

Hi folks, my first time here.

System:- ASRock G31M-S R2
Intel Q8300@2.5GHz
2TB HDD
120GB SSD

Dual boot Win 7 and Mint 17 Qiana
Mint is on the SSD

Old but a very stable system and reasonably quick, Mint 30 sec boot, 5 sec shut down,
it has served me well the last few years.

I decided to move up to Mint 19 Mate and that's when things went pear shaped with a
30 minute crash, the monitor turns off, system reset button dead, pull the plug.
This happens from a live DVD or a USB, if the computer is being used or if left idle.
Have tried other distros, Mint 18, Mint 17.3, Manjaro, Sabayon etc all hit the half hour crash.
Only Mint 17 Qiana and and old Sabayon 11 work.

Up to the crash the other distros work smoothly with no lag or other indication of problems so
I think the system is capable apart from this glitch, any ideas please.

That should tell you your gear is too old for newer OSen. You may need to look at Antix or MX Linux, or perhaps Puppy.
