Windows 10: Sign in Failure after update leads to crashes every minute

Ok so I have the Sign in disabled text on my laptop. I have never had any problems with it until last update. I’ve deleted the update and reinstalled it since it said it was corrupted but then my pc started freezing and blue screening every hour. I’ve tried everything to fix it and nothing works. And now I was trying to move my save data for my games on a usb but it now crashes every minute so question is. What is the optimal way for me to completely reset my pc and get it to work while only keeping the files I want instead of all of them?

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?

GPU-Z 0.8.7 crash on launch

W1zzard is asking you to test so that he can suggest next steps and be able to troubleshoot the issue you have.
If another version works, it would be one set of steps.
If several other versions also fail/crash, then it would be another.
