BSOD Created Minidump with Driver Verifier. Need help to read it.

Hi,

I am haunted by BSOD for some months now (approx 1-2 per week). They mostly occur during some RAM intensive things (videos, skype, image processing, antivirus check). I am pretty sure it is memory and/or driver related. I unsucessfully tried various things to fix it yet:

- Changed Ram, run memtest86 for 10h+. Everything ok.
- Checked Ram Voltage. No change.
- Reinstalled Windows7. No change, they quickly returned.
- Changed Antivirus Software. Checked for Malware. Ok
- Updated several Drivers, including graphic card driver

Now I run Driver Verifier and just got a Bluescreen. However, I am not able to completly understand which driver caused it. The latest Bluescreen has these information. Please help me to understand it.

Best Regards,
Zodurac

Hi Zodurac.

This issue is not seeming to be a driver related one.

Code:

BugCheck C4, {13e, fffff98059e10fd0, fffff98099e10fd0, fffffa8009a9dc80}

Probably caused by : Npfs.SYS ( Npfs!NpRemoveDataQueueEntry+a5 )

But something interesting is there about your RAMs.

Code:

  Size                          4096MB
  Form Factor                   09h - DIMM
  Device Locator                DIMM4
  Bank Locator                  BANK3
  Speed                         0MHz
  Manufacturer                  Manufacturer03

Code:

  Size                          2048MB
  Form Factor                   09h - DIMM
  Device Locator                DIMM3
  Bank Locator                  BANK2
  Speed                         0MHz
  Manufacturer                  Manufacturer02

Code:

  Size                          2048MB
  Device Set                    [None]
  Device Locator                DIMM1
  Bank Locator                  BANK0
  Speed                         0MHz
  Manufacturer                  Manufacturer00

You have two different types of RAM?

Can you keep the 4 GB one only, remove both the 2 GB sticks and see what happens?

Another thing is the RAM speed .... 0MHz! I am astonished .... but I am not able to explain it. I will request essenbe to comment on it.

Zodurac, If you would and if you don't already have it, please download CPUz (CPU-Z CPUID - System & hardware benchmark, monitoring, reporting) and install it. Please post screenshots (Screenshots and Files - Upload and Post in Seven Forums ) of the CPU, Mainboard, Memory and SPD tabs. On the SPD tabs, you can select each dim slot from a dropdown box in the upper left. I only need the Dimm Slots that are populated with Ram.

It is, as Arc said, never a good idea to run 2 types of ram. Ram should be purchased in kits. Kits are tested by the manufacturer to run well together. Individual sticks are not, and in a lot of cases wont.

I need you to also run this test and download it from the link provided.

I would like you to run memtest86+. It is quite a long test as it needs to be run for 8 complete passes all at the same time. Please download the test from Memtest86+ - Advanced Memory Diagnostic Tool. Although the names atr similar, this testis much better than memtest86. It needs to be run for 8 complete passes or until you get an error. If you get an error, stop the test. In the link above if you will go down to the middle of the page you can download either the ISO file which needs to be burned to a CD by Windows image burner or any disk image burner you choose. Or you can download the auto installer for USB Flash drives to run it from a flash drive. Whichever you choose, be sure to download the zip file and extract it. Each Pass consists of 10 tests, each pass checks a different thing and each pass checks different things. It takes a minimum of 8 passes to completely check the ram, more passes are better. It will take quite a number of hours to do the test, so it is usually better run over night. To run the test, boot from the media you chose and don't press any keys, the test will run automatically and will continue running until you tell it to stop. It will tell you how many passes it has run and how many errors are found. If it finds errors they will show up as red lines at the bottom of the page. It will take somewhere around 9-10 hours to check my computer with 8 GB of ram. If you have more it will take much longer.
