Windows 10: Programs crashing

Its been a longtime dealing with this ive tried insanely long to fix this issue with no avail in some regions programs would just shut off randomly and crashlogs would lead me to deadends. ive had repairmen take my pc in ive done incredible ammounts of work fixing it but i cannot get it to work, unity games in particular crash like this.heres 2 older forums of me trying to get help. ive seen so many strange errors done so much research and ive lost my mind fixing this.ill send a mega with some of my crashes and files to see if you can help. ive grown so tired of this.if you need anything else

:)

 

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?

 

Why did the startup window get cleared?

I didn't missed any step, the list was gone and gone , even after using lot of programs the programs were not listed in that list.

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.
