Windows 10: What is causing this crash?

I keep having an issue where around 2 hours into playing the game modern warfare 2 my PC crashes with the stop code DPC_WATCHDOG_VIOLATION, I tried everything including wiping the whole PC and doing a fresh install of windows. I will provide the DMP file and the V2 Log Collector zip file.https://drive.google.com/drive/folders/15oaGeQs2nVkddCgu6LuiMbR8FUbpxJUi?usp=sharing

GPU-Z 0.7.5 causing crashes on load up

Any chance you could narrow it down to which running application causes GPU-Z to crash? Ideally steps to reproduce for me here.

 

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?

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.
