Windows 10: Windows keeps crashing

I am able to boot up the PC and log in. Then it crashes and restarts with the error code: Critical process died. After the reboot it just shows: Reboot and select a proper boot device.I am able to do that and enter the bios. Under the boot options it used to show UEFI options but I clicked "reset UEFI to defaults" and now they are gone. But even when I still had them, Windows would not properly boot.

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?

 

Windows 10 keeps crashing

Hi,

There are many possible reasons why the computer will keeps on crashing. One of which is missing or corrupted system files. For us to further isolate the issue, we suggest answering the following questions:

• What exactly are you accessing/doing when the computer crashes?
• Were you still able to login to the computer after it happens?
• Can you send us a screenshot of the error messages or mini dump that you've received?

In the meantime, if you're seeing a blue screen when the computer crashes, we suggest following the steps on this article:
Troubleshoot blue screen errors. Kindly choose the appropriate answer to the category
"When did you get the error?".

We'll wait for your response on this matter.
