I'm Stumped, can't figure out what part is faulty. Random restarts!

[Sevan]

Ok so friday our pc at work was just fine. From what i am being told. Today all hell broke loose.

Once signed in within a few min restarts, so i get a free monitoring software and check the CPU temp. spiked 85c then restart occurred. So we changed out the CPU fan. Like an idiot i forgot to take off the sticker and it was restarting even faster cause of overheating. Fixed that and still. Then thought it was the nvidia driver cause in the programs like it had todays date, so i thought faulty driver, since  i just fixed the cpu overheating. Nope. I tried to restore windows to a previous date and it failed to do power issue. So i changed the power supply. Now it stayed up and running for maybe  15 min now psu, new cpu cooler and no nvidia driver. then crashed again.

So now i am left with either RAM and or SSD or the RTX3060 is bad its self. I tried reading the event log but this is a grey part for me and am not well versed in it. What can i do to figure out the issue. It happened so randomly. Easy was is just grab a new pc till i have the time to sort through this one. No since this pc has a software that is configured in a server install. Really just plain networking of the needed files and folders. It is a dental design software. If i leave it at the log in screen the dongle and database are readable on the network and the team can work this way, but the pc is useless and the scanner connected to it is down. This is not a server just a Asus ROG Strix GT15.

Thoughts?

Bad power switch?

But it is stable when left on the log in screen. Wouldn't a bad switch trigger the restart there as well?

So this may or may not help.

I had my computer randomly restart n shut down on me would happen maybe once aday or other times 10+ times a day i swapped PSU, graphics, moved stuff on the PCIE slots tried different memory all of it.

So much so i even sent my PSU off to see if it was faulty because i did a PSU swap and seemed to fix the issue only for it to stat up again weeks later.

 

The problem as far as i can tell was the power switch or the header cable for it because i removed that from the MOBO and it hasnt restarted or shutdown once since.

 

Check to see if it still does it while the power switch is unplugged if that doesn't fix it not sure.

High temperature doesn't cause restart, the desktop would only throttle. 85° ain't so bad.

I'd replug/reseat everything carefully.

Check your Ram with TestMem5 or Memtest86.

If you had a non-F cpu you could try without the gpu.

Fair enough, I will unplug the case headers from the board.

85c is not high you are right, but CPU overheating can cause restarting so that why I swapped the cooler out. Ill do a mem test if it can stay on, maybe ill do it in safemode and see.

Memtest86+ or PassMark Memtest86, both are bootable, they do not run from inside the OS.

Unplugged the power button header stayed stable for 8 min then restarted. I guess memtest is next.

unplug anything non essential, that includes fans, fan controllers except cpu fan or pump.. any other USB device, any other than boot disk.. all front panel connectors. 

then test if it still happens. 

i've seen disk usb devices, fan controllers, ram, mainboard, psu etc...  causing irregular reboots. for that matter cpu's too. but newer cpu's should just throttle past 90C or something.. someone first at 100C.. and not realy care about rebooting. 

 

If you have a samsung boot drive, make sure to download samsung magician and check if you need firmware update.. as they with original firmware are known to suicide.

In  the  end  of troubleshooting a local repair guy came in said with the Asus Z390 boards the wifi pcie goes bad, sometimes the wifi pcie bord or the mobo, this one was the mobo, we pulled the wifi card out and it still thought it was in there. So time for a new board, or pc. 

 

Thank you to everyone who tried to help me out. Much Appreciated.
