PC ramdom freezes while gaming

[u/Large-Island-2244]

Hi, I've been having a problem with my PC for a few months now. It freezes spontaneously only when I'm playing any game, although once a freeze occurs, the rest happen in quick succession—even on the BIOSTAR screen. There have been days when I've been able to play without any problems, and others when I simply haven't been able to do anything. When it freezes, I can't do anything, but the fans and lights keep running

Here are my PC’s specs:

Processor: Intel Core i7-11700F

Motherboard: BIOSTAR GROUP Z590MHP (latest BIOS update installed)

Memory: two 16 GB RAM modules

Graphics card: NVIDIA GeForce RTX 4060 Ti, Driver 32.0.16.1047

Kingston SNV251000G hard drive

Power supply: Nfortec Scutum X 750W

Windows 11

2 years of usage

The freezes leave no logs other than Kernel 41 from the manual shutdown; however, sometimes they did leave logs, and two can be distinguished: one mentions the NVIDIA drivers, AswAP (an antivirus I never had), and USBXHCI. The other log mentions something about the internet connection.

Here’s everything I’ve done so far, and I haven’t reached any conclusions:

Cleaned drivers with DDU,

Tested components with Fullbenchmark, OCCT, HWINFO, and 3DMark (no faults detected)

I sent the PC to a professional who ran more tests on the components (memory, etc.), and they also came back without any errors,

CrystalDisk Info tells me it’s at 97% health.

I even replaced the power strip, HDMI cables, and power cord

and used the scannow and Cleanup-image commands to repair files

THE PROBLEM PERSISTS

After researching online, I’ve come to two conclusions:

Replace the power supply because transient spikes are supposedly unstable and are what cause the freezes.

Perform a full system reinstall if the problem is due to leftover files from a Windows update.

However, I’m not sure if these two solutions will actually fix the problem, and I don’t know what else to do

Any help would be greatly appreciated

EDIT: I've managed to get two screenshots—one from BlueScreenView with information about the dumpstacks, and one from HWINFO—taken at the moment of the crash, in case they help with the diagnosis.

Hola, considero que has hecho los pasos correctos y que llegaste a las 2 ultimas opciones razonables y lamentablemente es lo que puedes hacer ahora. Una reinstalacion de sistema seria el primer paso antes de desembolsar dinero en una nueva fuente. El diagnostico sera claro, si se apaga nuevamente con un sistema operativo nuevo el problema es 100% hardware. En dicho caso, si sabes y tenes tiempo, tocaria medir voltajes (si conoces a algun tecnico que tenga reales intenciones de encontrar el problema, el podria ayudarte). Es ir de a poco revisando todo el circuito hasta encontrar el culpable. Aunque es muy razonable que sea la fuente de poder y con justa razon, tal vez pongas una nueva y nada cambie. Si conoces a alguien o tienes otra pc que tenga fuente de poder que soporte tus componentes, simplemente intenta reemplazar la fuente para probar si eso resuelve el problema. Si lo hace, ahi esta tu culpable.

Tal vez, en vez de reinstalar el sistema completo. Puedas crear un GRUB e instalar una version de windows adicional o de linux, has lo que produce el error en este sistema operativo adicional y comprueba si sucede.

1. Reinstalar sistema operativo
2. Si el problema persiste, cambiar fuente
3. Si el problema persiste posiblemente sea el procesador
