PC turns off suddenly

[ElCattivo]

Hi Guys,

during gaming, my PC suddenly turns off. Behaviour is: suddenly the system switches off (no shutdown), after cutting power and waiting for about one minute I can switch it on again and everything is fine.

First I thought of a temperature issue and used AIDA64 to take logs but the temperatures seem totally fine. What is a bit suspicious from my point of view are some peaks in the power consumption of the CPU and at the same time downward peaks at the GPU. Of course I don't have the log files from exact the moment the system switches off but I atteched some from one session where the system crashes about 2min later. 

Does anyone have an idea if these peaks are normal or any other suggestions about that?

my Specs:

Intel i7 12700K
Gigabyte Z690 GAMING X
Gigabyte GeForce RTX 1 3080 Ti Gaming

Many thanks

Steffen

i had this issue in the past.  it was sensor collision problem with a Corsair AIO water loop and AIDAs polling module that would randomly shut down the computer with no warning.

Try exiting AIDA and see if it contnues.

I recently got my sensor panel up and running.  It has been amazing until recently.  Constant shutdowns.  I have had this system functioning for the last 6+ months with no crashes.  Since these shutdowns have started I have updated BIOS, defaulted EXPO speeds, not doing OC so nothing to change there, did a clean install of Windows, and nothing stopped the crashes.  I am still crashing even with AIDA64 closed.  Might be RivaTuner server causing it.  Waiting for it to crash again.
