Windows 10: Unexplained PopFxEnforceDirectedPowerTransition crash

My brand new Dell laptop with Windows 10 installed crashes every now and then in sleep mode. I can't tell from the dump file what driver is causing this. Dell blames it on Windows and is asking me to reinstall it like the reinstall will magically realign drivers. I uploaded the most recent dumps to OneDrive https://prologika-my.sharepoint.com/:f:/p/teo_lachev/Et7OBmfNX4tAuum2NKvW_zEBoD5nePin0GbQdnlYMj-OAw?e=QUBlCbWhat can be done to pinpoint what's causing this?

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?

 

Unexplained crashing

I wasn't quite sure what I should now be doing to solve the problem. Eight days on and the PC keeps crashing.

Any suggestions gratefully received. Thank you.

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.
