Windows 10: Nearly all of my games crash on opening

Hello,This is a semi re-post. But I have more information now so I hope it helps get me an answer.Almost every game I open crashes my computer. If I happen to get it open, there's no guarantee it stays open while I play. Good chance it crashes in the middle of me playing. When I say "Crash" I mean, screen goes black, computer turns off, computer auto resets. I almost never get a blue screen of death, which means I almost never get any dump files created.The most common errors that appear in the Event Viewer which display probably 1/20 crashes are:nvwgf2umx.dll, ntdll.dll, "Game".exe for exa

:)

 

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?
