Windows 10: windows crashing BSOD , Need help

Its been 3 or more days ,my laptop suddenly give the blue screen with stop code error , i did not write down all of them as i dont have chance to read them as laptop was restarted before i can note it down. But today only once i note down was Stop Code: MEMORY_MANAGMENT , already ran windows memory diagnostics tool on reboot and there is nothing found.
But i am sure its not same stop code everytime i get blue screen.
I have attached my log using V2 Log Collector and it attached here.

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?
