Question PC restarts while I'm gaming ?

[Sonic_1g]

I am recently facing an issue where if i am playing any heavy games, my PC reboots and then has no display.

PC Specs
Mobo: Asrock B650
CPU: Ryzen 7 7700
GPU: XFX RX 6900 XT
RAM: Corsair Vengence RGB 32GB (16GB x 2) rated 6000mhz
PSU: DeepCool 850 watt

The RAM is set to default 4800mt/s, that's another issue, it won't go to 6000mhz despite enabling the profiles and setting it manually but it wont work, just displays blank boot.
Now the main issue is the pc reboots whilst gaming , There's no heating issues, temps are pretty fine with all components

I tried a few fixes from reditt like:

• Updating bios
• Having everything on default
• Playing with different versions of the adrenaline
• Deleting corsair icue ( someone on reditt said it causes issues )
• Testing every component individually and combined with OCCT

But no fix so far

My pleasure. Have fun!

The issue persists hehe, probaby the gpu is faulty
