Windows 7: random BSOD, used driver verifier and multiple crashes generated

random BSOD, used driver verifier and multiple crashes generated

Hello everyone, I am getting lost trying to troubleshoot my BSOD problem myself, I sincerely thank you for your help in advance. All my knowledge is from Google searches, please assume I know nothing regarding IT...

Summary of History:
1) Jan this year: Bought laptop Sager NP7270 with a Samsung 850 EVO M.2 SSD 500GB HDD, chose Windows 7 professional 64bit as my OS installed on above m.2 SSD. For personal use: gaming, websurf, media, email, etc.

2) Started getting random BSOD during normal everyday use, no detectable pattern and times. My then current guesses-- possible sound driver clash w/Sound Blaster Cinema 2 and Realtek audio (since opening laptop I've had unresponsive issues with SB Cinema 2). Tried uninstalling SB Cinema 2 but I'm unable to (error, unable to). Also, issue with losing sound when resuming from hibernate/sleep.

3) March 20th: Decided to clean install with prepackaged drivers and OS disc. Did not install SB Cinama 2. All seemed well, except still getting no sound after resuming from hibernate/sleep-- realized if I go into sleep again and resume, sound will come back.

4) April 8th: hit with first BSOD after clean install, then subsequent random BSOD next few days (see below screenshot of bluescreenview BSOD crashtimes).

5) Sometimes during these few months: Ran SFC config, results normal. I also did run a HDD check (through Windows), and no errors. Also, ran standard Windows Memory Diagnostic, results normal.

6) Yesterday: ran 13hrs (8 passes) of Memtest86, 0 errors. Also ran 1 pass of Memtest86+, 0 errors.

7) Today(4/21): Ran Driver Verifier using this tutorial, and all sorts of problems arose-- Most or all of the logged crashes are from shutting down (improper shutdown) during my restarts, and I wouldn't even get an actual bluescreen (it just resets). Also, while Driver Verifier was on, computer would be very sluggish. Internet connectivity would be very sluggish. Firefox would crash multiple times. My wireless mouse would stop responding suddenly (I'd have to use touchpad).

After each crash I would look at BlueScreenView and try to Google the Bug Check String/stop error code, and also the driver causing issue, but I fail at finding the solution as I don't know how to figure out the pattern. Below is a screenshot of my BlueScreenView:

And here is my log file: DEOWBA-Thu_04_21_2016_233700_86.zip

Again, your help is greatly appreciated!

Driver verifier

You are seeing all sorts of different errors, like I was...

Here is what I did on mine to pinpoint the problem.

Ran driver verifier with default settings, on all drivers. rebooted and fired up stuff intil i got a BSOD.
Took the newly created memory.dbg file from c:\windows and loaded it into WinDBG.

It told me what device driver was creating issues.

Hi deowba,

Welcome to the 7forums

I strongly recommend that you visit the support page of your laptop manufacturer and install all updated drivers.
There are several different drivers flagged, most of them are outdated.

Thank you both for responses. Should I follow through with both your solutions? Perhaps axe0's first, go to Sager support for updated drivers; then follow with sphenic's advice on driver verifier on default and then winDBG...?

Driver verifier isn't necessary, the drivers that caused the crashes are already shown in the dumps and I've done the Windbg part for you

I see, well thank you very much axe0! To follow up on your instructions:
1) do you have a list of those drivers that are outdated, i.e. are there certain ones I should have more priority in updating?

2) once I've updated, should I run any sort of test to verify stability?

Thank you again (sphenic too), and thanks guys for having me. I'll touch back once I've completed your instructions.

1. It is pretty generic, I noticed quite some drivers so I recommend that you go through the list provided by Sager.

2. I prefer to suggest to test under normal circumstances.

axe0, I went to Sager's support page and found my laptop's list of updated drivers. After installing the chipset and intel driver, I double checked the driver versions they offer with the ones I'm currently using. It turns out they're the same.

Here is the link for Sager's updated list of drivers for my NP7270 laptop.

All drivers listed are the same versions as mine, except the below few:
Bluetooth (I disabled this device instead as I don't use)
Integrated video camera (I disabled this device as I don't use as well)
Killer Wireless-AC N1535 Wireless LAN (I don't have this in my machine)
Intel WiDi Driver for Windows 7 64 BIT (I don't think this is installed on my machine)

To add, I also discovered in my device manager "Microsoft Virtual WiFi Miniadapter" w/drivers from 2006. As I don't plan on using this service, I disabled as well.


My question is does this mean my drivers are actually most up to date with the Manufacturer's? And where do I go from here then?

Update and reinstall the drivers, it then appears that some 'up to date' drivers are using a very old driver that caused crashes.
To explain, there are multiple drivers for the same thing, 1 of those drivers is very old while others are up to date, the other drivers is the onces you likely see.

Alright, I've reinstalled all the drivers from Sager's list. Only 2 I didn't install are Bluetooth (I couldn't figure out which folder of drivers to choose from- 7265 or 8260) and Integrated Video Camera. I just kept them disabled from my last post above (disabled under device manager).

1) Will this be ok?
2) Now, we wait and see through normal laptop use? When should I check back to mark thread as solved?

Thank you again.
