Hi my new pc.

12900K with NZXT KRAKEN X73 ( 40-50C in Far Cry 6 )

2x16GB DDR4 KINGSTON DDR4 3600MHZ in GEAR 1

RTX 3090 Ti Gigabyte Gaming

Aorus Z690 Elite DDR4 bios F5
 
Seasonic 1300 W Prime PlatinumPX

SSD 1 TB NVM PCIE

I went from Aorus Z490 and 10850K to 12900K and Aorus Z690 Elite DDR4. Windows 10 is installed on SSD from 10850K build.When new pc booted i enabled in GEAR 1 XMP ( 3600 mhz ). Then i rebooted to UEFI again without issues.

Then i reboot pc again and when windows 10 was loading pc shutts off and turns back on again. And second time it booted to Windows 10 normally. Is my pc fine? Why pc shuts off ( OFF ) and turns back again on first time,when windows 10 was loading ? Pc not rebooted. Pc shuts down and boot itself up. Not typical reboot.

It happened before Windows 10 boot <%>Getting devices ready. Pc just shutdown and rebooted. Happened once. Now its ok. Should i worry ?

Yes happened once on first time. So its ok? After Windows 10 is working i tested few games and no issues. 

I read the title and knew the author without looking. lol
Like everything else, if it happens only once, it isn't possible to troubleshoot. I wouldn't worry about it.

Someone said this to me:"

PSU shouldnt click during software install. If it reboots on its own after PSU shuts down and restarts there is a setting in the BIOS to restart on power failure. May have been a utility problem that was coincidental unless you are running a UPS.

PSU shutting down isnt normal but several reboots while detecting hardware is normal."





So what to think now?

I think you should be fine. Just use it now and enjoy it. Don’t over think it. If it happens again a couple times then you can troubleshoot

How many times has the computer shut down unexpectedly?
And how long ago?

Then it could have been anything
Maybe it was supposed to do that
Let it go and just enjoy your new system

Very hard near impossible to troubleshoot something that happened once and never again

I ask because my first motherboard was faulty. Whenever i turn it on all the leds and fans turn on for a half second then turn back off again, repeat forever. I cleared CMOS battery. Unplugged GPU. Removed 1 stick memory the same.
My friend come with hes mobo Z690 and all parts working fine with hes mobo. So i went to shop and they exchanged me Aorus Elite Z690 to other example and second motherboard booted fine.
So thats why i ask. Is that psu/shutdown ( psu click ) and reboot on new motherboard just before windows 10 was loading was somehow related ,that i have second motherboard faulty,or its completetly different thing?thx

Just my first motherboard ( that before exchange ) dont wanna boot. It stuck with boot loop. ON OFF ON OFF ON OFF. And psu was clicking too.
But new motherboard booted fine and its ok fine?

ok thx
