Windows 10: System Crashes- BSOD

SInce 26th Jan 2021, I am getting this BSOD error pretty often whenever I play any game. Sometimes it says CRITICAL_PROCESS_FAILED or SYSTEM_SERVICE_EXCEPTION. It is not creating any dump file as well even though it is enabled. When I checked the system logs in Event management there are 2 errors. One for the system crash BSOD and another is "Dump creation failed". Can you please help me out here?


These are my laptop configs-

Laptop model- Acer Predator Helios 300 2019

Processor- i7 9th gen 2.6GHz base, 4.5Ghz turbo boost

GPU- nVidia 6 GB RTX 2060

RAM- 16GB DDR4

Storage- 256GB SSD and 1TB HDD

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?

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 with unstable system

latest update,
I have changed psu for xfx 750W and keeping to stock values and use on board graphics, the system seems stable , has been for several days. If I try to unleash, then Its prone to occasional crashing.
So next step was to put HD6950 in with CPU in stock setting.
System very unstable again. crashes after about 5 mins.
I have lots of fans , CPU temp ~35deg, HDD ~30deg,
HD6950 ~ 49deg
When system crashes, I dont get bSOD but a grey screen with thin black vertical lines. I then have to re-boot . I get back, Windows reports error with usual 124 error.
Could the CPU be an issue ?
Dont have another to test.
Any suggestions ?
Thank you
