If it is happening the same with Win and Linux, then I'd guess it's a hardware issue. Remove your boot disk (whatever it is), throw it into another PC, and see if all is well. As to what hardware exactly is the problem, this will be difficult to determine. You could then start swapping components. Also, the weather has turned much hotter recently, and my laptop is kicking out much more heat. Try booting your PC in a fridge and see if it starts up ok. Or a bed of ice?

Unexpectedly and suddenly, my not-so-old daily driver PC has just given up. It boots but either freezes or reboots after between one and three minutes of activity.
It looks like you have tried all the obvious things.
First thoughts:
Before everything else: Make sure you have a backup. That may involve removing the disks and hooking each to another computer.
How can you run memtest in less than three minutes?
It sounds like an overheating problem. You've tried to address that. Grasping at straws: are there any fans on components that are not spinning? The processor says that it is happy. You've removed the video card. Are there any other fans just for one componenet?
If you go to the firmware ("BIOS") settup page on boot, and you let the machine sit for three minutes, does the machine reboot or freeze?
Have you tried reseting the "BIOS" to default or factory settings?
Years ago, I was surprised how often a power supply misbehaved. So I keep a spare in stock. But I haven't needed one for at least 15 years.
