Windows 10: Trying to diagnose mysterious crashing

I had to do a clean install last month, and I've been having mysterious crashes/reboots since—never when I'm in front on the machine, of course..dmp and .nfo files can be found here: https://drive.google.com/file/d/1hakY1DU2BncS9O4FFzsqu0AHCBCFHK2d/view?usp=sharing

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?

 

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.

 

Diagnosing a system crash

Hello,

This computer is crashing and failing to produce minidumps. This computer had been operating in a stable way for the past three years, and it was already used then. This happens some days (up to five times), not on others, and using any software or not.

Config:

W10 Pro, 1803

AMD A8

The description of the issue is:

• The screen immediately goes from black
• The screen shows the bootup screen.

I can also "hear" this happen since the fans blow hard during post. Since I enabled minidumps (~3 weeks ago) there have been no dumps saved, even though there were crashes. In the Reliability Monitor it shows that there are "Critical events: Windows was
not properly shut down". Without a minidump to help diagnose the issue, I feel lost.

Thanks!
