Windows 10: Hard freeze/crash at idle, sometimes BSOD

Hello,I am experiencing hard crashes quite frequently, but oddly it is typically when my machine is idle. It is happening often enough such that my machine is nearly unusable. Anywhere from immediately to a few minutes after letting it idle, it freezes up and goes to BSOD DPC WATCHDOG VIOLATION or it just hangs there and I have to hard reboot/shutdown. Intermittently I have gotten WHEA errors 18, and I believe one code 19 as well. I should mention that this problem began happening in late April/early May, but then it seemed to just go away for about a month or so.My specs are:Windows 10 21H2

Random freezes or BSODs (In windows drivers)

Basically you need to go back to the step described in my post #121

As the freeze happens when you leave the system idle for a while it is most likely a driver associated with a background process that starts up when the system is idle for while. You might be able to search the event information logs to check which services started around the exact time of the freeze.

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.
