Windows 10: Windows crash

Recently my windows crashed and when i restarted the gpu is missing.In device manager it is showing "windows has stopped this service error 403".

My system specifications are

Acer Nitro AN515-42

8gb ddr4 ram

4gb radeon rx460x dedicated gputhe one that is missing

2gb vega 8 integrated gpu

Ryzen 5 processor

Also in amd settings, the rx560x option is missing in switchable graphic option

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.
