Windows 10: Garbled and illegible BSODs

My system has frozen 3 times in the last week with a screen that looks like this:


I assume that it is a BSOD because it is predominantly blue, but as you can see, it is illegible. Here are the results of the V2 collector: DOUGAL-(2019-08-29_11-24-38).zip I have also done two passes of memtest86, but no memory error was detected. Until last week I had never had a system crash like this before. What is going on?

:)

 

I recently upgraded to Windows 10 and now the titles in my Start menu are garbled and illegible.

I recently upgraded to Windows 10 and now the titles in my Start menu are garbled and illegible. I wish I could post a screenshot but I can't read any of the items.

OP - Start Menu is illegible?

 

Garbled Registry Entries

Thanks, will do.

However, the link that you referred to had another link to Microsoft site and it seems that this garbled characters are related to Avast Browser Cleanup that I'd uninstalled recently.

Will still run chkdsk and see.

 

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.
