Question PC reboots itself only after cold boot, but only when playing a game, then it works fine ?

[Ender_h3o]

My spec:
Cpu:intel core i7-6800k 3.4GHz 6-core
Motherboard:msi x99a gaming 9 ack
Ram: G.skill ripjaws X 16Gb(2x8Gb)
Gpu: msi geforce rtx 3060 12Gb
Cooling: corsair h100i rbg
Ssd: samsung 850 evo 250gb
PSU:fsp group hydro g 750W 80+ fully modular ATX

Got 2 more ssd and one hdd for storage and game install directory

No event related registered at the time of the crash(just some security things, audit...)
Except the kernel-power 41 (power or faulty component)

Already tried with and without:
-OCgenie
-ICUE
-MSI Center
-geforce experience
-antivirus software

Nothing found on:
-sfc /scannow
-DISM.exe /Online /Cleanup-Image /Checkhealth
-temperature monitoring
-memcheck86+

Sometimes I hear a ticking sound, pour falling? But why ONLY on cold boot? What change on hardware side between cold boot and regular?

My previous GPU was causing tdr_failure BSOD(asus strix geforce gtx 980)(since 4 years) though it was faulty, still got nvlddmkm errors sometimes in event log but windows recover it since the gpu change.

And on each "crashy reboot", I got glitching audio during 2 sec, then after the reboot, I need to reset my motherboard to have Bluetooth working again. But working fine after that, even after 5 hours of heavy load on everything(cyberpunk with maxed out graphics)


My guess is PSU or motherboard, but hardware debug is like sorcery to me...

Welcome to the forums, newcomer!

Motherboard: msi x99a gaming 9 ack
What BISO version are you currently on for your motherboard?

PSU:fsp group hydro g 750W 80+ fully modular ATX
How old is the PSU in the build listed above?

What OS are you working with?

Sorry, forgot to specify, I'm running windows 10 pro 22H2,
The PSU is 6 years old, and the bios version is E7882IMS.370

Got an hint, I think it's the PSU having power capacity loss. I will change it later and update this thread
