Windows 7: Random BSODs. Drivers are up to date and Hardware has gotten the A-OK

Random BSODs. Drivers are up to date and Hardware has gotten the A-OK

I reinstalled windows thinking the OS was eaten up by some magical virus. Updated all the drivers. I've Run Windows extended Memory diagnostic and tested the Hard drive both came back clear or errors. I am at my wits end. It is my first build only about 2 months old. BSOD started only this past week other wise it was a smooth build.

Microsoft Windows 7 Ultimate: x64 (SP1)

Hello GEMdewy.

Stuff we'll need
  • A nfo file
    • Quote:
      To get this: Start Menu -> Type msinfo32 into the Search programs and files box -> When it opens, go to File, Save -> Save as msinfo32.nfo and save in a place you will remember -> Let it finish the process of gathering and saving the system info -> Right click the .nfo file, click send to compressed (zipped) folder -> Upload the .zip file here.

BSOD Analyse

Anyway, I'm suspecting 3rd party drivers are borking the pool caller. Let's do some stress testing on your drivers.
Using Driver Verifier is an iffy proposition. Most times it'll crash and it'll tell you what the driver is. But sometimes it'll crash and won't tell you the driver. Other times it'll crash before you can log in to Windows. If you can't get to Safe Mode, then you'll have to resort to offline editing of the registry to disable Driver Verifier.

So, I'd suggest that you first backup your stuff and then make sure you've got access to another computer so you can contact us if problems arise.
Then make a System Restore point (so you can restore the system using the Vista/Win7 Startup Repair feature) - and create a System Repair Disc (Win7) if you don't have a full installation DVD.
You can do this by going to Start...All Programs...Maintenance...Create a System Repair Disc (don't forget to test the disc to make sure it works).

For Vista, you can download the repair discs from different websites. If unable to locate them, shoot me a PM and I'll point you to them.
For Win8, BSOD's are different - and we'll have to adjust how we do this with them.

Also, to ensure that you can recover, here's another couple of additional steps:
- Get to the Safe Mode menu (rapidly tap F8 just before the Windows splash screen comes up). Scroll down to and select "Disable automatic restart on System Failure"
- Get the RED information from this picture (in particular we will need the name of the file that the error occurred in):
Picture of a BSOD

Then, here's the procedure to run Driver Verifier:
- Go to Start and type in "verifier" (without the quotes) and press Enter
- Select "Create custom settings (for code developers)" and click "Next"
- Select "Select individual settings from a full list" and click "Next"
- Select everything EXCEPT FOR "IRP Logging", "Force Pending I/O Requests" and "Low Resource Simulation" and click "Next" ("Special Pool" may be able to be used depending on amount of RAM and errors being seen. In situations with small amounts of RAM, DO NOT select it),
- Select "Select driver names from a list" and click "Next"
Then select all drivers NOT provided by Microsoft and click "Next"
- Select "Finish" on the next page.

Reboot the system and wait for it to crash to the Blue Screen. Continue to use your system normally, and if you know what causes the crash, do that repeatedly. The objective here is to get the system to crash because Driver Verifier is stressing the drivers out. If it doesn't crash for you, then let it run for at least 36 hours of continuous operation (an estimate on my part).

Reboot into Windows (after the crash) and locate the memory dump file. If present, turn off Driver Verifier by going back in and selecting "Delete existing settings" on the first page. Then, zip up the memory dump file(s) and upload them with your next post. If no dump files were generated, post back for further suggestions.

If you can't get into Windows because it crashes too soon, try it in Safe Mode.
If you can't get into Safe Mode, try using System Restore from your installation DVD to set the system back to the previous restore point that you created.

If that doesn't work, post back and we'll have to see about fixing the registry entry off-line:
Delete these registry keys to stop Driver Verifier from loading (works in XP, Vista, Win7):
        HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\VerifyDrivers
        HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\VerifyDriverLevel

Sorry about the delay. When i did get around to doing the verifier it blue screened on bootup. I encluded three dump files first being what reminded me to do this and two following were casued by the verifier i think.

When I use Verifier and the system crashes, then I take a binary approach.
I halve the drivers to test. Then just keep going, cutting in half until I locate a faulty driver. Then one starts again , after correcting the bad driver, until one has located and fixed all bad drivers

Now here is another approach: Use NirSoft's DriverView
DriverView: Loaded Windows Drivers List

Sort the resulting display by date of the driver. You are looking for drivers that are pre-2010. The ones that came with Win 7 are OK.

Quite often the problem is the ahci chipset driver. On this aspect you need to go to the website of the mobo and update the bios and any other drivers newer than what you have.

I know others have great fear of updating a bios. I've never had any problems. The last time I did a bios update was today.

Cut the amount of drivers in half like i think you suggested, it crashed nearly an hour later. After i tuned off the verifier a new BSOD came up. Loaded up both dump files.


Are the drivers i narrowed it down to by the time of the new BSOD. Don't really know what to do from here. Should I disable special pool in the verifier so it can run longer? or what?

You can ignore:

Why don't you do me a favor and google the other three to make sure that a) you need them, b) that they are current.

ALWAYS include new upload with you current post and not with a prior post.

Did you investigate DriverView?

Oops, I thought I put in a new upload my apologies. gdrv.sys and applecharger.sys are the ones that seem to have recorded problems. Both are gigabytes drivers. gdrv.sys is for an energy saver program. I swiftly deleted that pointless when attempting to OC, which i was planning on doing. Applecharger.sys is on/off driver, I don't charge stuff with my computer off so I plan on deleting this once I find it. I uploaded what I should of uploaded in my previous post. If it helps you confirm that these two are the ones to blame. Thank you so much any which way.

I did find the drivers that I could do without, they have been disabled. Everything was working fine. I even was able to put my computer under load via prime95. Satisfied with a 12 hour run, which it couldn't do before I thought the problem fixed. Today, forty eight hours later, I get a new Bad_pool_Header BSOD. I ran chkdsk /c and it came back error free so I did as karlsnooks asked and included the lists of my programs, the newest dump file, and a screen shot of the chkdsk. Good part of me is hoping this problem is related to the earlier stuff. Ockham's razor don't fail me now! Thanks for the help as always.

first, I'm going to ask you to run CHKDSK X: /R for each and every partition you have.

Substitute for X: the actual partition (drive) letter.

Do NOT make any snapshots. Do not worry about the results.

I will give you instructions and a little script which will bundle all of the chkdsk results up for you.

Now with that out of the way, I'll look at the 3 files I requested.

Oh yes, don't go disabling a driver just because you think you don't need it.
