Why is my PC shutting down?
Why is my PC shutting down?
My PC frequently shuts down and I found similar problems on forums where CPU cooler/PSU were the issue. But no one shared results matching my Kernel event 125. Can someone clarify what AC0 and related terms actually refer to?

Welcome to the forums, newcomer!
My computer frequently powers off.
We need more details—what activities are taxing the system to cause shutdowns?
Power Supply: EVGA 850 Gold
EVGA is the manufacturer, while 850 and gold refer to the PSU's wattage and efficiency rating. Could you share the model number and its age?
Processor: Intel Core i7-11700K @ 3.60GHz
Cooling: Cooler Master Hyper 212
You might have the incorrect cooler for this chipset.
When sharing a troubleshooting thread, it's standard to provide full system specifications. Please list them clearly:

Add the PSU age and current BIOS version for your board.
Thank you! And sorry for the inconvenience.
This issue began recently, sometimes it bypasses the post and occasionally stops before posting a few times, then restarts repeatedly until reaching the win login screen.
It’s typical for my computer to turn on and remain active for 10 to 15 minutes before shutting down and restarting again.
After about 30 minutes of this behavior, it usually stabilizes and runs smoothly for hours. (I understand it’s not ideal)
I mostly use this machine for gaming and streaming, and it was originally a pre-built system that I upgraded over the years, covering nearly all components.
CPU: Intel Core i7-11700K
CPU cooler: Cooler Master Hyper 212 (intended upgrade but set aside and neglected)
Motherboard: ASUS TUF Z590-PLUS WIFI BIOS Ver 1017 (onboard network card isn’t functioning)
RAM: G Skill DDR4 2x16
Storage: 980 PRO 2TB SSD, ADATA XPG SX8100NP 512GB (Windows drive included in 2020), WD10EZEX 1TB (not currently used but also pre-built in 2020)
GPU: 3070 TI Super (2024)
Power supply: EVGA 850 GT Super Nova 80+ Gold (bought early in 2022)
Case: Lian Li LANCOOL II W/USB C

I recently acquired these items: NZXT H9 Flow, NZXT Kraken 360mm and NZXT C 850W 80+ Gold.
