Windows 10: nightly BSOD crashes

Hi all, I recently fitted a new cpu and 4x4gb memory sticks to my pc and now it crashes every night. I've run stress tests on both CPU and GPU and both came out fine.

I see these messages in event viewer: Critical19/10/2020 03:02:30Kernel-Power41(63) - The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

Winver: OS Build 19041.572

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?

 

Random BSOD while browsing internet


BitDefender is nothing special. mwac.sys causes BSODs anywhere.
A tiny documentation can be found here: Solved Random BSODs - Windows 10 Forums
In that very thread, the suggested action apparently worked.

The storage and network filters of any third party antivirus can cause BSODs. Neither MBAM nor BitDefender is any special. For a regular antivirus, it may be shifted to an alternative; but MBAM has no alternative. So a clean install of the said program is the most feasible first step.
As far as the first step is not failing, it is better to not think for the second step. Because the BSODs are not universal, failure at the first step is not universal; and success at the second step is also not universal.
That is why I posted that my suggestion may work, or may not. Let us see where it goes.

 

BSOD when watching Netflix and Hulu

This is becoming a constant and it's incredibly frustrating. Every time I'm watching something on Netflix or Hulu my computer crashes to the BSOD! I have no clue what to do.

I've tried running diagnostics tests, clearing my cache, updating drivers; nothing seems to work! This began occuring right after upgrading to Windows 10. With the exception of the nightly BSOD when I'm trying to unwind and go to sleep, Windows 10 has been
running beautifully.

Please help!! I'm not particularly tech savy, so if there is a step-by-step guide it would be greatly appreciated
