Windows 10: Windows BSOD Crashing Unpredictably

Good dayMy PC is crashing unpredictably and increasing in frequency over the past few months. It happens more often when I play Dota 2 Legion TD Reborn arcade games.It crashes seldomly on low loads or idle but it still does, unpredictably.I get WHEA_UNCORRECTABLE_ERROR as the BSOD message most of the time. Only once has the PC crashed and not shown a message but I've tried a new PSU, still crashing.Specs:Ryzen 5600XAsus Strix x570-iCorsair DDR4 3600MHz 16gb x 2Samsung 500gb SSDHP EX950 1TB NVMeNVidia GTX1070No overclocking has or is done on this system since purchase.I have tried:BIOS Up

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.

 

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.
