Windows 10: System crash

i was playing a game and for some reason i closed lid of my laptop. after two minutes when i opened my laptop it was showing some error don't remember what it was exactly} and then it says please wait and few seconds later it asked for pin to unlock windows but when i entered pin it showed some error code ....... idk what no was that and then a pop op opened to enter microsoft account but i wasn't connected to internet so the process could not happen . and i restarted my laptop from the power option shown on lock screen and when i entered pin now it opened. so any way of checking why that err

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?

 

all games crash!

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.

 

Help! New system keeps crashing

It's runing through them now. It's a step forward, as the problem was the system crashing as soon as I pressed the key to boot from the disk, it crashed before I even got to install it. When it's done, I'll burn another copy, see if that works.
