Aurora r7 boot

the endless and proper question is the problem HW or SW, hard or software

ever boot to live linux boot USB stick< see if linux is happy?   Costs is 1 usb stick at walmart for $5

lots of things can cause this,

only 2 common things self shut off any PC,

• Overheating. CPU, and with modern GPU it to can shut down, too hot. (it also slows down first , too hot)
• or the south bridge messes up (software told it to)  The South bridge runs power controls. all of that.

if linux boots fails, then that tell me its #1 above

if not Linux happy (test media) it's #2,  and hard work to find it.

On some PC there is BIOS page for autopower on AND off, Dell does'nt document BIOS, so all I can do is wiggle my fingers through the BIOS pages to find, it, see on servers and workstations. not game boxes  mostly.

The OS can shut down too, if scheduled to do that, (for example in Task Scheduler ! JOBS present.)

that OS , ?  what was there before? W7 or 8? ,or nothing a new SSD. I can't guess what you did. sorry./

how did w10- get there, by  cold booting a USB stick and fresh install?

or a UPGRADE mode.?

if you upgraded, it you get all those other things(SW) that mess with power, now present in the new W10.

why mess with insider preview? 

It is lame Beta software?, (you be the lab rat and fall on your sword, for MS?) why run this, then tell anyone but

MS your wow s?  it;s there  CUT.  their magic,  tell them>?

me what I'd  do is stay away from Insider, and load the current working w10 1903 to  usb stick and do a fresh clean install of the robust 1903.  (run only the newest stable version  never run beta stuff)

run the one marked as safe for business (hint hint)

You can try to see if you can boot into safe mode consistently without the auto shutdown issue. If yes, at least you know it’s a driver or some higher level software and not the problem with the OS kernel itself.

Ya I'm thinking its that.. it literally started up after installing insider.. dumb move by me.
