Windows 10: Hardware error make my computer crash

Hi guys, I hope finding the help I need here. I have build a computer for some time now and recently my computer kept crashing when I'm playing games. At some point, all screens 2 monitors become black, still hearings the sounds but nothing responding. I need to shutdown the PC and open it again and it can happen a few times per day.. Can someone help me ?

:)

 

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?
