Windows 10: windows 10 crashes every day several times

I got a W10 Pro. It is crashing at startup or during working every day> Today it crashes 3 times after log in.

Bluescreen dumps aren't created although i enabled this. I did a repair install, but that didnt help.

I checked the memroy but that did give an error.

I already asked this question a few weeks ago, but i didnt get an answer anymore and now the question is compeltely gone.
I checked the eventvwr for error during the crash, but it is difficult to find something. Several crashed in a row makes that difficult.

Help?

:)

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?
