Windows 10 blue screen reboot loop ? Attempted to write to readonly memory

We only have one customer who is not a business.
They are the sweetest elderly couple and they?ve called us for years.
Today I had one of their computers in because it was blue screening. It?s a custom built machine that originally had Windows 7 on it but has since been upgraded to Windows?8 and then Windows 10. With an SSD hard drive, it usually runs pretty well .. until the?day it got itself stuck in a reboot loop.
The problem with an?SSD on an UEFI?BIOS is the thing is just so fast to boot, you?often can?t interrupt the process with F8 or Shift + F8 to see if you can get it?to start in Safe Mode. Most of the Windows 10 blue screen reboot loops I?ve seen have been AMD graphic driver issues, so that?s what I incorrectly assumed with this one.
I should have gone with my logical troubleshooting skills, when the error read ?Your PC ran into a problem and needs to restart. Attempted to write to readonly memory.?
Yes, that?s a pretty big clue right there. Memory.
Booting off a USB key with my favourite utilities and running Memtest86 confirmed it:

New RAM it is then. Sorry AMD.
And lesson learnt. Read the error messages.
