Windows 10: Screen crashes when running games

This is me running a GPU benchmark. 5 minutes into the benchmark, small black squares started popping up and glitching around the screen. Usually it just blackscreens and I cant do anything, but i got one BSOD that had the error code of "Memory Management". This crash usually occurs when I try to run intensive tasks.System Information:Ryzen 5 5500u with Vega 7 graphics8gb LPDDR4X RAMNvidia MX450Windows 10/11I have already tried using installation media, many times, installing windows 11 and 10, I did the windows memory diagnostic thing, I reinstalled GPU drivers with DDU, and did all the SFC /

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?

 

all games crash!

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.
