Windows 10: GPU crashes .

Hello i have a really huge problem regarding with my GPU. Bought yesterday from amazon.co.uk this laptop and it's a Acer Aspire 7 with ryzen 5 5625U , RTX 3050 , 16 RAM , 512 SSD Issue is that my gpu keeps crashing when im joining a game, As example i'm going on league of legends, the game starts and after 10 seconds my game goes black and like refreshing the GPU or smth like that and after few seconds the image comes back, but again after 10 seconds it goes black and so on untill my whole computer freeze and then it stops freezing and the game is crashed. I tried to fix it by :- Reinstall Win

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?

 

GPU-Z 0.8.7 crash on launch

W1zzard is asking you to test so that he can suggest next steps and be able to troubleshoot the issue you have.
If another version works, it would be one set of steps.
If several other versions also fail/crash, then it would be another.

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.
