Windows 10: random crashes and freezes?

I'm having problems with my PC crashing and freezing. It seems random, even crashing when I'm not in the room but I've left the computer on. There is no error message. The screen just goes blank and computer stops or on other occasions the screen just freezes. Thanks

:)

 

Random Crash/Freeze on Build 10130


Hello everyone.

I have been running the Windows 10 preview for the last few months and other than a driver issue here or there, did not experience any real problems. However, with the last update to build 10130, I have been experiencing a random crash/freeze that manifests itself in one of two ways:

1. If I step away from the computer and come back before the monitor is set to go to sleep, I will come back to a frozen cursor, unable to do anything.
2. If I step away from the computer and come back after the monitor has gone to sleep, I will come back to a black screen, unable to do anything.

In both cases, I have to hold the power button in to shut down the computer for a restart.

Any direction or help would be greatly appreciated.

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.
