getting stop codes:memory management/ dpc watchdog violation /attempted write to read only memory

[ouzaloid]

Hello community,

I have HP elitebook 840 G3, bought reconditioned 2 weeks ago, windows 10 64bits.

I randomly get a blue screen, each time with one of the following stop codes:

•  memory management
• dpc watchdog violation
• attempted write to read only memory

the computer then remains for few seconds on that blue screen and restarts. it then works with no problem for several hours before having that same problem again.

I have tried many solutions without finding the cause of the problem:

• I checked and installed all drivers I could find
• I ran  the command : chkdsk /f /r 
• I ran the  mdsched.exe
• uninstalled newly installed softwares
• scanned for viruses with Windows defender and Mcafee
• I ran sfc/scannow
• I ran a RAM check with memtest86 tool
• I ran HP PC Hardware diag UEFI SMART and extended tests on the SSD, both tests passed
• I ran  PC Hardware diag UEFI Memory quick check, test Passed

I tried to do a recovery but as the device is recent, I can't find a recovery point older than when the problem started, so may be I have to restore windows from scratch ?, in that case will I lose Office 2013 license that came with the device ? (office license name: office15_KMS_client edition)

please is there anything else to be done for that blue screen error or this PC must to be returned to sender ?

thank you

Thanks, I've installed the files as you proposed,

However, I didn't get any window message or confirmation upon installing the battery tool and the intel management firmware, the installation wizard just opens the black command prompt at the end of installation and nothing happens later, I suppose this is normal and that's how it's supposed to work?

anyways, after installing the last one{Intel Management Engine Firmware} I got a windows notification [at the bottom right of the screen next to the clock] saying: "Intel ME Wireless LAN update unsuccessful" 

In order to test the computer I would need to wait for few hours/days to see if the blue screen stop code comes back again or not, and will let you know.

Thank you

Hello Ub6424

I ran the commands, these are the messages I got respectively:

msdt.exe /id WindowsUpdateDiagnostic  ===> troubleshooting couldn't identify the problem

Dism /Online /Cleanup-Image /ScanHealth ===> No component store corruption detected.
The operation completed successfully.

Dism /Online /Cleanup-Image /CheckHealth ===>  No component store corruption detected.
The operation completed successfully.

Dism /Online /Cleanup-Image /RestoreHealth  ===>  The restore operation completed successfully.
The operation completed successfully.

all checks are OK so may be we should try something else?

in the meanwhile, I've restarted the computer and will let you know of updates

Hello Ub6424,

the computer was working perfectly since my last message, but unfortunately right now I've just got that blue screen and restart, the message it showed this time is:

• "page fault in non paged area"
