Hello, since this morning I've been having issues with my computer randomly blue screening. I've done research, updated some drivers, and listened to some online advice to get the most info possible. At this point it feels like I've exhausted every avenue for someone who isn't really great with computers and doesn't really understand the information I've been given. I would really appreciate some help and a big thank you to everyone who responds to this thread!!!

Hello! Thank you very much for replying, it says the uploader files is too large for the server to process for the sysnativefilecollecionapp.

 
The below as a starting point;

Windows Defender
Windows Defender: Enabled

Firewall: Enabled

Display Name: McAfee Firewall
Antivirus
Windows Defender
Antivirus: Enabled

Virus Signature Database: Up to date
McAfee VirusScan

Virus Signature Database: Up to date

Having more than one AV or Firewall installed on your computer is bad, it will slow down the computer, cause internet connection problems and leave you with no AV protection at all if they cancel each other out as they fight for resources.

Windows 8, 8.1 and 10 come with an improved Windows Defender, it offers the same real-time anti-virus/anti-malware protection as Microsoft Security Essentials. Windows Defender also shares the same malware signature definitions as Microsoft Security Essentials, and Forefront Endpoint Protection. Technically, Microsoft Security Essentials has not been renamed Windows Defender, or combined with it in Windows 8, 8.1 and 10.

If any AV product that you have is a paid for version you should always make sure that you have a copy of the product key kept somewhere safe just in case you ever wish to reinstall it.

Malwarebytes removal info here

McAfee product removal tool (MCPR) info here

Once any other AV has been correctly uninstalled, check to see if Windows Defender has auto enabled and allow it to update and carry out a full scan of your computer.

I have uninstalled both and full scanned it came up with nothing. Just to make sure things didn't resolve itself I left my computer running and it is still BSODing.
 
1. Copy any dmp files from C:\Windows\Minidump onto the desktop.
2. Select all of them, right-click on one, and click on Send To> New Compressed (zipped) Folder.
3. Upload the zip folder using the Attach button, bottom left of the dialogue input box

Can I ask that you do not quote every reply as we have to read the full post to make sure nothing gets missed,, thanks.
 
Right, apologies for that.
The file was too large to send through the attached files and wouldn't process. Again a googledrive of the zipped folder if that's fine. Thanks again.
 
Sorry but can we have the dmps the way that they were requested, your method is wanting me to download a third party extractor which I am not prepared to do, only dmps that are between 1 and 3 days are any use and using my means of getting the dmps to us can more than handle the amount of dmps you have.
 
Each crash was caused by the same thing Bugcheck 0x18 REFERENCE_BY_POINTER which amongst other things was a known problem with McAfee, see thread here

Your latest crash dmp is a couple of days old so we need to see if the same crash happens again, while we wait, can you post a new Speccy url for us, no rush here as I`m going offline now.
 
The first two crashes were the same as all of the previous but the latest was caused by either plug n play drivers or an actual PnP device failing, first thing we need to do is check to see if we can see any orphaned McAfee or MBAM files that may have been left behind, once done we will look at the PnP issue.

When you post the Autoruns log can you also let us know if the first two of the latest crashes were before or after McAfee and MBAM had been uninstalled and had the the computer been restarted since their removal, both points are important for us to know.

Post an Autoruns log for us, see here

1: Extract the Autoruns Zip file contents to a folder.

2: Double-click the "Autoruns.exe".

3: Click on the "Hide Signed Microsoft and Windows Entries” option.

4: Go to File then to Export As or Save in some versions.

5: Save AutoRuns.txt file to known location like your Desktop > when you click on File > Save you will then get the option to Save as type, click the drop down tab, change it to Text and then click the Save button.

6: Attach to your next reply.

Yes, I believe they were uninstalled when those crashes happened at the very least I'm sure one of them were. Another crash happened as I was trying to do all this.
 

Attachments

Same Bugcheck 0x18 REFERENCE_BY_POINTER crash as the majority of your other crashes.

There are still traces of McAfee on the computer, use Autoruns to find and delete the following entry, see To Disable or Delete? info here for "how to"

"mfencbdc01" "McAfee Inc.: " "" "File not found: \Device\mfencbdc01.sys" "" ""

I recommend that you also uninstall EasyAntiCheat as it is renowned for causing problems, plenty of examples here
 
I removed the remaining McAfee file and just to play safe removed a malwarebytes extension and just restarted. It looks like easyanticheat is necessary to run certain games so I'll keep it for now as it doesn't seem like loading multiplayer games is an issue.
 
It doesn't seem like the other crashes are happening anymore which is fantastic as they were a lot more frequent I may be able to use this computer to get things done now, thank you so much for that!
The other crashes have been going on for a bit longer and I think I've noticed have mostly or always happened when my computer went to sleep. I'd turn it back on and it would ask for recovery options.
