CPU: 9800X3D GPU: MSI GAMING TRIO 5070 TI MB: MSI MPG X870E CARBON WIFI 7 RAM: CORSAIR 32Gb 6000MHz PSU: MSI A1000G 80+ GOLD AIO: MSI MAG CORELIQUID I360 FANS: (6) MSI EZLIGHT SSD: •What is happening? since two/three weeks ago i think i started having this issue where my pc randomly shuts down, it happened while i was gaming, while watching YouTube, while studying i really dont see a pattern here. anyway, it will randomly happen that the pc shutsdown, all at once, no BSOD no freeze, no signal. just goes off all at once. Windows event viewer gives a Kernel Power 41 (63) with no other events related to this before it.

•What i tried so far: i reinstalled gpu, chipset drivers with DDU i update my bios to the latest version i ran many stress tests with superposition and OCCT(mostly) tests that i ran: GPU+VRAM(every version i think), CPU+RAM, POWER TEST no errors detected, no shutdowns, temperatures where normal (CPU at 86°C, GPU at 60°C) i ran sfc and DMSI updated to latest win version Memtest86 passed with no errors

•What i still have to try Reseat every cable try using a diffrent power cord installing windows again

i dont think its an hardware problem, the tests wouldnt have passed if it was the case I think, i also noticed that my 12V 5V and 3.3V readings are kinda messed up (respectively they display 24V 7,5V and 3V, but i think its just an error as other voltages are normal) the only thing i can recall doing before this started happening (literally same day) is using the Nvidia app fine tuning and putting "prefer max performance" , which i then disabled and set settings to default. the only pattern that i noticed (probably wrong tho) Is that every time this happened i was online, it happened that while i was playing a game, the game said "network error" and then the PC shutdown. just to precise: all the cables came with the PSU, except the 12vhpwr which came with the gpu. i have no overclocks, nor i ever overclocked this pc i had the pc for about a year, but this gpu only from Christimas 2025, this is genuinely making me insane if anyone can help me that would be much appreciated, thank you. if you need other info ask in the comments, i will replay asap.
