Discussion PC Restarting while gaming

[Sonic_1g]

I recently am Facing an issue where if iam playing any heavy games my pc reboots and then has no display.
Specs:
Ryzen 7 7700
Asrock B650
Gpu Rx 6900xt xfx
Corsair vengence rgb 16x2 (rated 6000mhz)
Psu deep cool 850 watt
The ram is set to default 4800mt/s thats another issue it wont 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 rebooting 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

What CPU cooler are you using?

What you described is often the signs of a heat and/or power issue.

I am leery of your PSU/GPU combo. The 6900 XT can be very picky with PSUs, quite demanding.

Have you had this issue since you built the system? Or is this a recent development?
