Windows 10: Need Help with Crashes

Hello, i've been having this problem where my screen will go dark, as if it was dimming the light, and then restart, no message at all on the screen, it only happens in certain games so far, but i've tried games that i've played before without problems, and now this happens, already did a clean driver install and it didn't help, i'm going to check if it restarts when running benchmarks aswell. Anyone experienced something similar ?Specs areX570 e gaming5900x3090ftw 3 ultraRog Thor 1200w

all games crash!

I suggest you run rthdribl > http://www.daionet.gr.jp/~masa/archives/rthdribl_1_2.zip
Increase the window size step by step and watch your vga temps permanently.
What happens?
If it crashes, run at stock speeds as suggested before and retry.

P.S.: When your system locks, does the display signal turn off after a time?
Stuttering sound or no sound at all when freezing?
What X1800XT model do you own exactly?

ive watch my temps and both the cpu and gpu are within normal ranges. when it freezes it simply freezes the image and stops the sound. i must reboot to get back to windows.
