Gianmarco · Aug 6, 2023

Hi all,
I'm new here and I'm asking your help to understand and, hopefully, solve the bsod in the object. This error show up when my computer is turn on but wiht nothing running, I tried the common solution found surfinge around the web but they didn't work.. Ah this evening changes the BSOD in PAGE_FAULT_IN_NONPAGED_AREA, but it's the same, during dinner the bsod arrives and my pc is rebooted. Everyday.
Here there is a link at the last log I did: BSOD
Thank you for your help, hope I did everything in the right way.

Added another log to the same folder for another 2 bsod UNEXPECTED_KERNEL_MODE_TRAP

These are usually very difficult to debug unfortunately because the call stack is often trashed. We may need to employ some educated guess work here.

Could you please open an elevated command prompt and enter the following command:

Code:

fltmc filters

Please provide the output in your next post.

Please perform the following steps:

1) Run Tuneup plus:

Post a share link into this thread using one drive, drop box, or google drive.

2) Run Memtest 86 + for 8 or more passes.

Run the testing overnight while sleeping and during the next day.

The computer has 32 GB RAM.

Testing time is approximately 1 -2 hours / GB.

The RAM modules can be tested at the same time or one module at a time in the same DIMM.

Just 1 error is a test fail and testing can be aborted.

II run the win native memtest without errors or other problems. But i'll give it a try during the upcoming weekend

zbook · Aug 7, 2023

For RAM testing please use Memtest 86 +.
Make sure that a minimum of 8 passes are completed for each module.
Take pictures > post images or share links into this thread.
It sometimes takes more than 20 passes to find malfunctioning RAM.
Just 1 error is a test fail and testing can be aborted.

Isn't MemTest86 the better one to use with UEFI systems? And might want to mention that they may need to complete two separate runs of 4 passes as I believe they have limited it with the free version.

The native Windows version isn't very good at testing for issues, which is why everyone usually recommends MemTest86 instead.

Please create a restore point and then open an elevated command prompt and then enter the following command:

Code:

pnputil /delete-driver oem2.inf /uninstall /reboot

Afterwards, please check that gameflt is missing from the list produced by the fltmc filters command. If it is, then please continue to use the system as you normally would and then run MemTest86 during the weekend.

I've done it, but the gameflt is still there (I rebooted the system also)

I see, thank you for the hints!
I downloaded the latest version but it doesn't boot from usb (secure boot disbaled), I'll try with another pen-drive... or there is some other change in the bios for the boot?

That's odd, it should be removed, when I've used pnputil with that driver in the past, it was successfully removed and wasn't registering with Filter Manager. Let's try the following FRST script:

FRST Fix
NOTICE: This script was written specifically for this user, for use on that particular machine. Running this on another machine may cause damage to your operating system
1. Download the attached fixlist.txt and save it to the Desktop.
Note. It's important that both files, FRST64 and fixlist.txt are in the same location or the fix will not work (in this case...the desktop).
2. Run FRST64 by Right-Clicking on the file and choosing Run as administrator.
3. Press the Fix button just once and wait. If for some reason the tool needs a restart, please make sure you let the system restart normally. After that let the tool complete its run.
4. When finished FRST64 will generate a log on the Desktop (Fixlog.txt). Please post the contents of it in your reply.

You might need to enable CSM support which is sometimes shown as legacy mode.

Thanks, looks like it completed with no problems.

It looks like both of those recent crashes were prior to the FRST fix and both were Stop 0x7Fs again. It's good that the crashes are consistently the same stop code at least as should be easier to isolate the issue. Let's see if the crashes still continue, if they do, then please upload the dump files again as you have done before.
