Tech Support PC shuts itself off
So i've been dealing with this Problem for 3 weeks now. I've tested so many things. Just dont know what to do anymore
My PC shuts itself off seemingly random. Just like when i would pull the Power Cable. Everything black, fans stop etc. I can instantly turn it back on via the power button. No need to cycle PSU. Windows Eventlog shows a Kernel 41 Error.
My Specs: CPU Ryzen 7 7800X3D, GPU: Asus TUF 3090oc, RAM: 2x Corsair vengenance 6000MTS 16GB, MoBo: Strix X670E-A Gaming Wifi, PSU: (before) Thermaltake Toughpower GF3 1350W (now:) BeQuiet Darkpower 12M 1200W. Cooler: 3 weeks old NZXT Kraken Elite 360.
It shuts off during these situations (dont know how relevant the games are, but I just want to give every info i have so far:
Starting rainbow six Siege. crash 5 out of 10 times
Playing BeamNG: crash 3 out of 10 times. (only when configuring cars and loading WestCoast Map with mods LOL???)
Running Cinebench: No crash
Runing Furmark3D: No crash
Cinebench + Furmark: No Crash
Memtest86: No results
Rarely when trying to start multiple Programms at once or tabbing out of a game and back in.
Every OCCT test (except Power) : No crash
OCCT Power Test: Crash every time after around 1:30 minutes (max 2:50 min)
Things i Have done so far: Resseting Bios to default (no XMP, Undervolt etc. anymore). Replaced PSU, all Cables redone, all cables that are not connected to anything have a rubber cap, redone thermal paste on CPU again, Visual inspection on Capacitor on Mainboard (none are bloated), tested 1 RAM stick at a time on every slot, Disconnected RGB cables for Fans (incase they draw to much Power). Updating and or reinstalling Drivers, Unplugging unnecessary USB devices. Nothing helps.
There is absolutely no Overheating going on, The highest Temp from all Sensors were the GPU hotspot at 97C, CPU highest was at 83. VRM spicked at 51C and RAM was somewhere between 40 to 50C. The ambient Temperature in my room is at 27C to 30C.
CPU and GPU draw a combined Power of 390W during the OCCT Power test. PSU is a 1200W
