Windows 10: computer keeps BSOD at random, even when at the login screen.

I've been having issues with windows 11 ever since i got it in dec 2021. sometimes the pc is fine for hours, and other times it keeps blue screening every couple minutes. the errors have happened when running basic apps, when web browsing, even idling on the desktop or the very login screen itself before i've even had a chance to sign in.I've checked all my hardware, and it all appears fine, with all the drivers showing theyre up to date. the only new hardware in the last couple months had been an upgraded graphics card and new ram chips, thinking the old ones might be the problem. the O/S

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.
