Severe system instability for Intel Arc A770 (16GB)

[KS_V]

I bought in January an Intel GPU; and recently, I have been experiencing serious system instability linked to the use of this video card. for the games I play (mostly shooters), the PC crashes after 5 to 15 minutes; and sometimes I can have like 3 hours and a half of pure fluidity.

For the games I play:

-Escape From Tarkov.

-Rainbow 6 Siege.

-Rainbow 6 Extraction.

-PUBG.

-Insurgency Sandstorm.

I noticed, most of the time, that DCOM errors were popping up, and most of the time it's:

- PerAppRuntimeBroker

- Windows.SecurityCenter.WscBrokerManager

- Windows.SecurityCenter.WscDataProtection

- Windows.SecurityCenter.SecurityAppBroker

I want to precise, that only the WHQL version of the graphics drivers are installed, the Re-Size BAR support is enabled, Above 4G decoding is enabled as well. TPM is on.

My Specs: MB: GIGABYTE B550M DS3H RAM: 2x16GB (Crucial I believe) CPU: AMD Ryzen 5 5600X GPU: Intel Arc A770 16GB (ASRock) SSD 1: Crucial P3 2TB (Windows) SSD 2: Crucial P5 2TB + heatsink (Parrot OS) PSU: 650W Aerocool.

P.S: system was reset a few hours ago; everything has been clean-installed.

I would like some help on that point since I am running out of options for fixes please

My personal thoughts are that your power supply is a bit light.

What I thought as well, but uncertain about that because some other games launch just fine. And, not to be doubtful or whatever; but I fail to see the link between power supply and DCOM, is there any explanation for it?
