Windows 10: what causes my BSOD?

Hello..while im browsing using firefox my pc suddenly get a BSOD. This is the 3rd time i get a BSOD. Can anyone help?Error code = ATTEMPTED_WRITE_TO_READONLY_MEMORY caused by usb80236.systhis is the dump file ATTEMPTED_WRITE_TO_READONLY_MEMORY beAn attempt was made to write to readonly memory. The guilty driver is on thestack trace and is typically the current instruction pointer.When possible, the guilty driver's name Unicode string is printed onthe BugCheck screen and saved in KiBugCheckDriver.Arguments:Arg1: ffffc98f8ec11000, Virtual address for the attempted write.Arg2

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???

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

 

BSOD Hardware Caused???

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