This problem started in August 2019 and has happened randomly ever since.
– 15x BSOD STOP D1 Errors, ALL in pci.sys.
– 4x BSOD D1 Errors in hal.dll.
– Also 8x other misc BSOD Errors, as per below:-
1- BSOD 7e + mrcbt.sys
2- BSOD 3b + ntoskrnl.exe
3- BSOD + msahci.sys
4- BSOD 9f + nvlddmkm.sys
5- BSOD 50 + ntoskrnl.exe
6- BSOD 0a + fltsrv.sys
7- BSOD 7e + mrcbt.sys
8- BSOD 9f + ntoskrnl.exe
The BSOD 7e in mrcbt.sys are being followed up with Macrium, so can be ignored.
I have 20 DUMP files to go with the above and have attached the last one, from the
26/Dec/20, as well as the “SysnativeBSODCollectionApp.exe” Results ZIP file.
[Currently I am having troubles uploading these files, even though the Dump is < 400 KB
and the ZIP is only 1.8 MB.]
I have attempted many fixes, after much research, but nothing has worked.
I have used Nirsoft’s excellent BlueScreenViewer, but it has inly confirmed that the
issues seems to be in pci.sys.
I can often trigger the BSOD by running a game; namely Rise of Nations or Age of
Also sometimes when the PC has not been Rebvooted for a while, but this is only a
(Usually, I just “Sleep” the PC.)
I also sometimes have the BSOD when doing something graphical, even if not taxing for
the system/graphics card.
And BTW, I have tried 2 different graphics cards, individually, of the same specs.
I have tried the following Steps to Diagnose:-
* # DONE # Step 1- Update Your PC Device Drivers
*- AMD Chipset Drivers Downloaded
*- AMD Mobo Drivers Downloaded
*- AMD Mobo Utilities Downloaded
*- Nvidia Drivers Downloaded
*- AMD Chipset Drivers Installed
*- AMD Mobo Drivers Installed
*- AMD Mobo Utilities Installed
*- Nvidia Drivers Installed – v391.35
– Cannot guarantee that pci.sys (offending Driver) was updated by the above Drivers.
P.S. I would love to know WHERE pci.sys lives; a constiuent of which Driver?
* # DONE # Step 2- Repair Registry Entries Associated with Applications, SDK/DDK
*- Win7 SDK Downloaded
*- Win7 SDK Installed
– No KNOWN corrupt Registry Entries.
– Malwarebytes (MBAM) Premium HAS cleaned some apparently infected Registry
Entries, but this was alongside an MBAM AI False Positive, so I am
a little sceptical.
– After consulting MBAM Support, the MBAM AI WAS proven to be a
False Positive, on Palm Desktop.
* # DONE # Step 3- Conduct a Full Malware Scan of Your PC
– I use one entire partition (F:) for ALL of my Downloads, not just a Folder.
ALL Downloads stay on this partition for a MINIMUM of at least 2 weeks,
but it is usually MUCH longer, prior to installing or being
moved to my default Data partitions.
– I run Kaspersky Internet Security (KIS) and run a Quick Scan every week.
I have significantly modified the Quick scan to scan much more than
– KIS auto-Updates itself at least once a day.
– I also run Malwarebytes (MBAM) Premium, with all the Protection settings on,
except for the Ransomware Protection, as it collides with KIS, and
– MBAM runs a Scan every day, after Updating itself.
– I also run other various Rootkit scanners from time to time.
x # NOGO # Step 4- Utilize Windows System Restore to “Undo” Recent System Changes
### ISSUES EXPERIENCED OVER A LONG PERIOD OF TIME
### SYS RESTORE HAS NEVER WORKED SUCCESSFULLY FOR ME; I PREFER RESTORES.
x # NOGO # Step 5- Uninstall Recently-Installed Program Associated with Applications,
SDK/DDK / Pci.sys
### TRIED TO NO AVAIL, SO REINSTALLED.
### ALSO, NOT APPLICABLE – ISSUES EXPERIENCED OVER A LONG PERIOD OF TIME
* # DONE # Step 6- Run Windows System File Checker (“sfc /scannow”)
### NO INTEGRITY ISSUES FOUND
### OVER MULTIPLE RUNS, OVER TIME.
* # IN-PROG # Step 7- Install All Available Windows Updates
x+- NO mandatory Windows Updates Available
*- Optional Windows Updates Downloaded
*- Windows 7 Quality Rollups
*- .NET Quality Rollups
### SYSTEMS IS AS UP-TO-DATE AS A WIN7 SYSTEM CAN BE.
*Step 8- Check for Hard Drive Corruption (“chkdsk /f”)
### I HAVE RUN A CHKDSK /F /R ON ALL MY 6X HDDs/SSDs.
### I ALSO DO THIS ON AN ONGOING BASIS, FOR MAINTENANCE.
?Step 9- Test Your Memory (RAM) for Corruption
### BECAUSE THE PC WAS SO NEW WHEN THE BSODs STARTED, I HAVE NOT YET
### RUN A RAM DIAGNOSTIC, PLUS IT IS CORSAIR QUALITY RAM.
x # NOGO # Step 10- Perform a Clean Installation of Windows
### WIN7 INSTALL ON RYZEN TOO COMPLICATED TO CONSIDER REINSTALL AT THIS TIME.
### ALSO, NEED WIN7 ISO WITH USB 3 DRIVERS STREAMED-IN 1ST & HAVE HAD VARIOUS
### ISSUES WITH ACHIEVEING THIS.
### NOT GOING TO HAPPEN – TOO MANY
### ISSUES WITH 1ST WIN7 INSTALL.
*Step 11- RUN SysnativeBSODCollectionApp.exe pgm from Bleeping Computer.
– SysnativeBSODCollectionApp.exe – v4.6.1
– Report produced (Zip) (1.8 MB).
[Currently I am having troubles uploading these files, even though the
Dump is < 400 KB and the ZIP is only 1.8 MB.
I will keep trying.]
STEP 12 – RUN Driver Verifier
– Would not complete successfully – BSOD STOP E6 Error, every time.
– E6 = DRIVER_VERIFIER_DMA_VIOLATION
– This Verifier issue & DMA violation certainly suggests a Driver issue
or Memory issue.
I am about to run Step 9, but thought I would Post this first.
I also need to update to the latest BIOS, but there are a number of these to do, with very special instructions and I currently do not have a UPS up & running, so must proceed carefully.
In the above Steps, a couple of things bother me.
The System File Checker (SFC) found no issues, over multiple runs and yet pci.sys
seems always to be the issue.
CHKDSK /f /r ran cleanly on ALL discs, including the system disc.
And yet, Driver Verifier will NOT run, suggesting Driver corruption.
– System Manufacturer
### CUSTOM – BUILT MYSELF
– Exact model number (if laptop, check the label on bottom)
– OS – Windows 10, 8.1, 8, 7, or Vista?
### WIN7 PRO SP1 X64
### 6.1.7601 SP1 Build 7601
– What was original installed OS on system?
### THIS IS THE ONLY OS TO HAVE BEEEN INSTALLED
– Is the OS an OEM version (came pre-installed on system) or full retail version
(YOU purchased it from retailer)?
– Age of the computer (hardware)
### DEC 2019
– Age of OS installation – and whether you have re-installed the OS
### ORIGINAL, NO REINSTALL.
– Laptop or Desktop computer?

As an ex-Mainframe Analyst/Programmer, I can read Mainframe dumps, but not x86 PC Dumps.
Although I know a fair bit about PC S/W and H/W, dump reading is not one of my skills.
I could use some help.
