What is causing my computer to BSOD at random times?

Anonymous

I have a custom built gaming PC that has recently been blue screening randomly and it seems completely unprompted. It happens when I'm in the middle of a game, or when I'm working on a Word document with Spotify playing, or when I'm browsing google chrome with nothing else open. I don't know what could be causing it.

The error I get is always "KMODE_EXCEPTION_NOT_HANDLED"

I recently had an issue where my computer would BSOD with the same error every time I woke it up from sleep mode. I got a warranty replacement for my RAM and that fixed that issue. These BSODs seem to be caused by something else. This also means that I find it highly unlikely that there's something wrong with my RAM.

Here is a link to the dump files I've gathered so far. I will add more as my computer continues to crash. It happens once every few hours, it seems.

Does anybody know what could be causing this issue? Do the dump files point to anything specifically that could be causing the crashes?

Thank you

Just for test, would you mind try boot into Clean boot and see if you are observing this behavior?

Have a look at How to perform a clean boot in Windows - Microsoft Support.

Interesting. I have an update for you as well. Just a few minutes ago I was working on google chrome with music playing and got a BSOD, with a different error message this time. This time it was "CRITICAL_STRUCTURE_CORRUPTION". It also said "What failed: ndis.sys" below that.

I added the dump file this crash created to the same folder that the other 3 files are in, linked at the beginning of this thread. Maybe that will provide us with more information?

Thank you again for all your help.

Hi Reza,

When I ran sfc /scannow I got this output:

Windows Resource Protection found corrupt files and successfully repaired them.
For online repairs, details are included in the CBS log file located at
windir\Logs\CBS\CBS.log. For example C:\Windows\Logs\CBS\CBS.log. For offline
repairs, details are included in the log file provided by the /OFFLOGFILE flag.

This isn't the first time I've had to do that, and last time I ran it there were corrupt files then as well. Could there be something causing the file corruption?

Thank you very much for your help

Hello Alex,

The 3 crashes were all caused by the instruction "mov cr0,rax", which is part of the sequence:

mov r12,cr0

mov rax,r12

btr rax,10h

mov cr0,rax

The odd thing is that this code is not in any driver - it appears to be code that has been copied into some allocated memory. This type of behaviour is definitely deprecated in Windows kernel-mode code.

It is not currently clear if there is enough information in the dump file to identify the source of this code. I will let you know if I find anything.

Open start and search for feedback and open the Feedback Hub app and report this issue and you may share dump files and other logs there. Open start and search for cmd and right click and run as administrator and then type the following command:

sfc /scannow

Press enter and let it runs and see what the result is?
