Windows 10: My laptop crashes for unknown reason

I managed to install Windows 10 on a external HDD on my laptop since my internal hdd is broke and i dont have a SATA connector for internal hdd..Everything is working fine i can run apps , run games without any problems, but for some reason when i decide to update my graphics drivers and after i restart my computer,it will shutdown automatically just after the login , i can resolve it by going to safe mode and remove the driver..But the big problem is that my battery is dead, so the only way to use my computer is by keep my charger plugged in, and works just fine but when i shutdown the system

BSOD Unknown Reason

The dump file on the 18th was caused by Quick Heal again. The later ones appear to be due to bit flips. I would recommend enabling Driver Verifier on all third-party drivers using the following instructions:

1) Search for verifier using the Start Menu and select the verifier.exe, accept the UAC prompt and you should be presented with the following screen:





2) Tick the following options as shown below





3) Ensure that you select the option to enable you to select drivers yourself





4) Select all drivers which are not Microsoft related and then click the Finish button. Afterwards, please reboot the computer and Driver Verifier will continue to run in the background. Please do not select the drivers which are prefixed with dump_

 

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?
