Windows 10: What could be causing this crashing and freezing.

I have had frequent 1-3 times a day freezing of video and audio, and for the past few months, I have been trying to solve the issue to myself and have not been able to fix it. I've tried dusting my computer, reinstalling windows, and updating my drivers. And now just today, at 2:00 my computer froze for I would say 30 seconds, and then just went to a black screen and booted itself back up. I went to look in the event viewer, and in the system tab of the windows logs, there is a critical error that says "The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly." No bluescreens, just an automatic restart by itself. I'm not sure what I should and should not give out, but if anything is needed, I can provide. The source is "Kernel-Power" not sure what that means.

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.

 

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.
