Windows 10: Windows 11 crashed with minidump

Hi all,My Windows 11 is running on Dell XPS 8940 desktop. I recently upgraded from Windows 10 to Windows 11. Meanwhile, I added two new DDR4 RAM and HDD disks to the PC.This PC becomes very unstable after its upgrading to Windows 11.I used to leave this PC running 24*7 without running any resource-intensive programs on it. It crashed very frequently. It crashes once or twice a week.By checking the Windows event viewer, I can find some errors.For example:The computer has rebooted from a bugcheck. The bugcheck was: 0x00000116 0xffffc38aa0bcd460, 0xfffff806517e6620, 0x0000000000000000, 0x000000

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.
