Question PC freezes when I minimize game ?

[Cursed Puppet]

Hello, I have this type of problem, when I playing games, usually CS2 and DOTA if I don't minimize game I can play without problems even whole day but when I minimize game with alt+tab or Windows button PC instantly freezes, for like 30s nothing happens , I can still hear discord, in-game voices , sometimes before restart it has voices like 30second happened in 2 second and it's just restarts , when I trun on pc again usually gpu driver is disabled and had to turn it on from device manager.

Have tried already:

• Reinstall Windows 11
• Reinstall GPU Driver
• Bios Update

OS: Windows 11
CPU : I5 - 14600KF
MB: AURUS ELIXE AX Z790
GPU: RX 6700 XT
RAM: Corsair vengeance 32gb
PSU: 750W Gigabyte

PSU make and model (or part number) is? Also, how old the PSU is, and was the PSU bought new or used/refurbished?

Try pressing following combo: Windows Key + Ctrl + Shift + B.

It restarts GPU driver within OS, without you needing to reboot.

Reinstall GPU Driver

Did you use DDU in Safe Mode when uninstalling old GPU drivers?

Since this is advised to do, when reinstalling GPU drivers. DDU will get rid of all lingering GPU drivers.

when I trun on pc again usually gpu driver is disabled and had to turn it on from device manager.

That indicates the fault with the GPU itself.

Try with 2nd, known to work GPU.

What is the serial number on your PSU?

Look it from the PSU's label. It is labeled as: SNxxxxxGxxxxxx, where each "x" is specific number.
Or take a pic of the label, upload it to e.g www.imgur.com and share the image here.

This is important, since that defines if you literally have a time bomb at hand or fixed version of the notorious Gigabyte P750GM series.

By any chance, do you play on different reso than your desktop reso is?

Since forcing to switch reso between the game and desktop can cause such issue.
