Windows 10: Random Windows Crashes

I'm getting crashes that seem to happen at random. They happen when the PC is idle, haven't had time to play games so I can't really say if they happen under load. There's no visible BSOD. The screen goes black and the PC reboots. I have a fresh install of Windows 10 Home, I had these issues before and decided to do a clean install. Drivers for GPU, Mobo and such should be the latest as of yesterday(11th Dec 2019).



PC specs:

Intel Core i7-3770k

8GB DDR3 Corsair Vengence LP

Gigabyte Z77N-WIFI Motherboard

Asus GTX 1660Ti 6GB

Corsair SF600 SFX PSU 80PLUS Gold



Here are crash logs:

In the logs I've also included DCOM Errors that show up in Event Viewer, not sure if these are related to the crash issues though.

Somehow I do suspect that this is a PSU issue, but I do not hope so since it's a quality PSU that shouldn't have gone bad by now.


Have I missed any info needed?

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?

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.
