PC reboot itself randomly

[Formattai]

Hello everyone and thanks in advance for your reply and sorry for my simple english

My pc keep randomly rebooting during the day. It no shows any error or signal and in device manager the only thing is Kernel Power 41, so is kinda generic. I've already reinstalled windows, runned some memtest with no error, updated the bios and all the driver of the pc,changed the psu and added a new CPU fan,tryed every combination of frequency of the ram in the BIOS but none of this has solved my problem. Also cleaned my gpu and reseated every power cable of the pc.

 

My configuration is:
CPU ryzen 5 2600
MB gigabyte b450m ds3h
GPU pulse rx570 8gb
Ram G.skill 16gb 3200mhz
PSU BeQuiet system power 9 600W
BIOS version : f60e

how often does it do it? also (this is probably dumb question) are you sure you don't accidentaly restart your pc somehow? (for example I have pc next to my legs and I sometimes rest my legs on my pc and I can sometimes accidentaly turn pc off since i have legs on it)

 

hmmm

unfortunately it does from 2 to even 10 times a day and I'm pretty sure that isn't rebooting from my movements (it reboot itself even when I'm away from the pc)

I don't it's a software problem, it's not a full reboot but more like a rapid loss of power but actually I don't really know what is causing this

CPU,MB,SSD,HDD are from 2018
GPU 2019
CASE,CPU FAN and PSU 2020
I have the suspects that may be the gpu, some days ago i pulled it out, cleaned it and pc run fine for 2 days, then it starts again to reboot. Also sometimes when reboot, gpu fan start spinning at max speed with no reason. I reisntalled the driver with ddu multiple times and also tried a lot of version (even the one from 2019)
Unfortunally i don't have a spare gpu and buy a new one is extremely difficult with this shortage, anyway how can i be sure that is the GPU?

Removed the backplate and the fan and cleaned the heatsink( i didn't remove this one 'cos i don't have spare thermal paste to replace the old one), also cleaned the pci connector with some alcohol

Cleaned like with air or what? Did you let it dry after cleaning with alcohol?

You cleaned it with fingers? You know static charge exists?

Not on the main board of the GPU, but I have the reboot problem since last august( but it was once in a while) not since i cleaned the GPU

oh... I assume you tried not even turning on pc for some time thoug you prob need it daily...

 

did you try just turning it on and not doing anything on it letting it run empty? (that prob won't prove or fix anything..)

The pc stayed off for some days in December but still got problems, and yes pc reboot even in idle (just turned off the pc didn't do anything and waited for it to reboot)

Also today I booted an ubuntu live usb and after a couple of hour i went back and found it rebooted it again, didn't know if this helps, but surely tells us that windows is not the fault

So it suddenly goes like blackscreen and turns off or what.

Aaaaalso, have you tried power & saving & whatever power settings? In these settings there are things like "30 min idle pc will go sleep" and stuff like that usually notebooks have this cranked up.
