Windows 10: KB5037591 Causing BSOD

I installed this update yesterday on my machine which is P3 Ultra. Today in the morning I had repeated BSODs. Yesterday I am assuming the update was successful but I did "update and shutdown".I rolled back using the recovery options to a date 10th of May and that did not fix the issue. In the recovery options then, I uninstalled an update it did not show me what it was uninstalling and it has removed KB5037591 & moved me back to KB5036620.The computer now appears to be working fine. No BSODs since then. They were very frequent in the morning like every other minute.. couldn't do anythi

BSOD Hardware Caused???

they do weird things like that, which all seem like something else is failing.
One of the worst things to diagnose, they seem to only quit when they want to.

Memtest is a good next step, if you rule out RAM and Power Supply make sure you disconnect all unnecessary peripherals and try to start the system with as little hardware as possible, if it works then, you can narrow down the culprit by trial and error.

the follow was taken from some website:

It's very difficult to determine if a failure is caused by the CPU because many other components can cause the same symptom when they fail.

1. System fails to boot
2. System re-boots intermittently
3. General Protection Fault
4. Illegal Operation
5. Stop Error, or BSoD (Blue Screen OfDeath)

Actually, CPUs rarely fail, and about the only way to determine if the CPU is causing the failure is to swap it out with a known working CPU of the same type and speed. Since this is difficult, the best bet is to first rule out every other possibility.

Before suspecting the CPU, rule out all the possibilities listed below.

1. The Operating System
2. A peripheral port device
3. A bad memory module
4. The hard disk drive
5. The power supply
6. The motherboard

If you have ruled out out all the other possibilities, investigate the items listed below.

1. Overheating
2. A short circuit
3. ESD

 

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 Hardware Caused???

It is not overheating - CPU runs 60*C in games.
Short Circuit - EXTREAMLY UNLIKELY
