BSOD due to ntoskrnl.exe (it's back again)

[toucan8]

And another today. Seems to be saying BAD_POOL_HEADER now. No idea what may be triggering it.

Update or reinstall the Realtek audio drivers and temporary remove McAfee.

 

[toucan8]

What do you mean temporarily remove McAfee? As in, do a clean reinstall? I had MalwareBytes installed (trial version) and I read elsewhere that it can cause the BAD_POOL_HEADER to occur, so I uninstalled it yesterday.

 

[axe0]

Temporary removing software means uninstall it while the problem is there in this case.


Windows 8 and up have by default Windows Defender, which is good enough if you use the basic ruless regarding security.

Been using the computer sporadically because of all the BSOD, but I turn it on and get another one. It's driving me nuts. Do you think it's still the same issue? View attachment PEGGY-Mon_08_14_2017_204515_59.zip

Something different.

Install the latest nvidia display driver from Dell, reinstall if its already the latest.

 

[toucan8]

Dell or nvidia? Crap I uninstalled nvidia with DDU and then reinstalled it from the nvidia driver website and I keep getting more BSOD. I think it's my CORSAIR keyboard or mouse but I don't know how to confirm it. Here are the latest dump files. I also removed McAfee with their uninstaller and reinstalled a new one (last week, prior to tampering with the nvidia drivers). View attachment PEGGY-Tue_08_22_2017_190410_18.zip

I'm getting the BSODs from hell. Just as I was going to post an update to one, I get another one 10 minutes later. Hoping I can quickly post this before it happens again. View attachment PEGGY-Thu_08_24_2017__73535_75.zip

Remove McAfee.

You need to keep it removed for a long time.

Temporary removing software means uninstall it while the problem is there in this case.

So then what do you think is going on now? Sigh, can't seem to win with this machine this past year. Always something popping up. Haven't made any changes to it though. View attachment PEGGY-Tue_10_24_2017_185742_97.zip

 

[toucan8]

And another one. Damn. This can drive a person nuts. 25 crashes in one year. To give you some background, I system restored it to a prior time before the crashes, but it seems like it didn't do anything.

Has McAfee been removed properly?

Start Menu\Programs\McAfee	Public:Start Menu\Programs\McAfee	Public

 

[toucan8]

I thought it was, but guess not. Is that's what's been causing my recent crashes? I hate them lol.

 

[toucan8]

Still happening. I definitely removed all McAfee products from my computer. I don't know what could still be causing it.

Please follow the below suggestions in the order posted.

Diagnostic Test

RAM

Run MemTest86+ to analyse your RAM. MemTest86+ - Test RAM - Windows 7 Forums

   Note

MemTest86+ needs to be run for at least 8 complete passes for conclusive results. Set it running before you go to bed and leave it overnight. We're looking for zero errors here. Even a single error will indicate RAM failure.

Make a photo of the result and post it.

Addition:
If errors show up you can stop the test, remove all sticks but 1 and test this single stick in each slot for 8 passes or until errors show, switch sticks and repeat.
If errors show up and you see them a lot later, no problem, the errors don't affect the test.

Driver Reinstallation

NVIDIA

Please uninstall everything of Nvidia using Display Driver Uninstaller and install new drivers from Nvidia. Be sure the clean install box is checked and only install the Graphics driver and the PhysX driver, you can use this tutorial to do so :ar: NVIDIA Drivers - Avoid Problems - Windows 7 Help Forums

Here is the memtest, it found no errors after 8 passes. I also followed the instructions with DDU and then reinstalled NVIDIA drivers from their website.

I'm back again with another BSOD even after all those previous suggestions.. View attachment PEGGY-Tue_11_14_2017_213759_98.zip

 

[axe0]

Very likely due to an issue with the latest Windows Update updates (read, driver instability from 3rd party).

Please follow post #2 again to run driver verifier.

 

[toucan8]

Ran it and nothing happened in 48hrs. Do I keep trying it? I thought the computer BSOD'd again but there was nothing saved as a dump.

 

[toucan8]

I'm starting to sound like DJ Khalid.. Another one. Happened right after I turned off driver verifier. This is driving me nuts. Thanks again for checking this out, axe0. View attachment PEGGY-Sat_11_18_2017_124316_86.zip
