I've been troubleshooting and have already -Uninstalled Norton Antivirus and installed Microsoft Security Essentials -updated Realtek driver from mobo website -updated nvidia driver -ran memtest86 over night for 8 passes with 0 errors -ran sfc /scannow and chkdsk /r from cmd line with no errors -disable driver verifier using cmd line verifier /reset and also checking registry for driver verifier keys which were not found Even after all this, I still received a bsod upon wake up with the driver verifier listed!!! I would love to add the zipped bsod file but don't see an option for this. Here is the information from bluescreenviewer though: ================================================== Dump File : 032412-12511-01.dmp Crash Time : 3/24/2012 9:30:36 AM Bug Check String : DRIVER_VERIFIER_DETECTED_VIOLATION Bug Check Code : 0x000000c4 Parameter 1 : 00000000`00000091 Parameter 2 : 00000000`00000000 Parameter 3 : fffffa80`069bc5c0 Parameter 4 : 00000000`00000000 Caused By Driver : NETIO.SYS Caused By Address : NETIO.SYS+5a4a File Description : Product Name : Company : File Version : Processor : x64 Crash Address : ntoskrnl.exe+7cd40 Stack Address 1 : Stack Address 2 : Stack Address 3 : Computer Name : Full Path : C:\Windows\Minidump\032412-12511-01.dmp Processors Count : 4 Major Version : 15 Minor Version : 7601 Dump File Size : 295,456 ================================================== anyone here have any ideas what I can look at next to fix this?

After searching all over due to a similar problem, I enabled Driver Verifier and got a BSOD loop caused by it after. Instructions to turn it off don't work. Says its off but it isn't actually. Got mine fixed by getting rid of verifier, posting here in case it helps someone googling! Fix! At least for Windows 10 - Boot into Safe Mode Find Verifier.exe and verifier.dll in C:\Windows\System Rename them. If you can't, force permission changes by taking ownership of the files and adding your permissions to allow renaming. Reboot! My core issue was a non-os data drive cable had come loose and was causing issues. This was immediately obvious after I got rid of verifier and was able to boot to the OS.

thank you for the replies. I have alreay ran the verifier /reset from a cmd (run as administrator). I also am unable to find the keys in the registry. I just did the search box disable as you suggested so I will see what happens. I will look into skydrive to upload the last minidump file.

Hi, The Bug_Check C4 CAUSE netio.sys which is a Windows component which means that something else drove it into Fault. Netio.sys caused BSOD are most often the network drivers (WiFi/Wireless or NIC/Wired) or the antivirus software (particularly McAfee is known to cause that one). You probably do not have DriverVerifier disabled.

BSOD from driver verifier yet driver verifier disabled

Hi,

Results verified by WinDBG, DumpCHK, and BlueScreenView.

BugCheck C4, {91, 0, fffffa80069bc5c0, 0}

Probably caused by : ntkrnlmp.exe ( nt! ?? ::FNODOBFM::`string'+4874 )

ntkrnlmp.exe is a Windows component which means something else drove it into Fault.

BiosReleaseDate = 09/01/2011 <- BIOS is very current however there may be updates to it,

the low level chipset drivers, and the major on-board and separate device drivers.

SystemManufacturer = Gigabyte Technology Co., Ltd.

SystemProductName = Z68X-UD3H-B3

BaseBoardManufacturer = Gigabyte Technology Co., Ltd.

BaseBoardProduct = Z68X-UD3H-B3

BaseBoardVersion = x.x

1. Use the suggestions in the previous post to update the network drivers and check the

antivirus program.

2. Check Gigabyte for updates to the BIOS, low level chipset drivers, and the major on-board

device drivers. Also update the major separate device drivers - run DriverView - set VIEW to

Hide Microsoft drivers - update those without Dump in their name.

Gigabyte Support

Gigabyte Downloads

3. Run the memory test - keep in mind that memory tests do not detect all errors such as

the tiny speed differences between modules that appear to be identical. So it may be

necessary to swap the modules in and out in different combinations and patterns (see

methods at the end of this troubleshooter).

4. Use the other methods as needed in the troubleshooter below.

References to Vista also apply to Windows 7.

This is my generic how to for proper driver updates : (Check for BIOS and driver updates.)

This utility makes it easy to see which versions are loaded :

DriverView - Free - utility displays the list of all device drivers currently loaded on your system.

For each driver in the list, additional useful information is displayed: load address of the driver,

description, version, product name, company that created the driver, and more.

http://www.nirsoft.net/utils/driverview.html

For Drivers check System Maker as fallbacks and Device Maker's which are the most current.

Control Panel - Device Manager - Display Adapter - write down the make and complete model

of your video adapter - double click - Driver's tab - write down the version info. Now click UPdate

Driver (this may not do anything as MS is far behind certifying drivers) - then Right Click -

Uninstall - REBOOT this will refresh the driver stack.

Repeat that for Network - Network Card (NIC), Wifi, Sound, Mouse and Keyboard if 3rd party

with their own software and drivers and any other major device drivers you have.

Now go to System Maker's site (Dell, HP, Toshiba as examples) (as rollback) and then Device

Maker's site (Realtek, Intel, Nvidia, ATI as examples) and get their latest versions. (Look for

BIOS, Chipset and software updates at System Maker's site while there.)

Download - SAVE - go to where you put them - Right Click - RUN AD ADMIN - REBOOT after

each installation.

Always check in Device Manager - Drivers tab to be sure the version you are installing actually

shows up. This is because some drivers rollback before the latest is installed (sound drivers

particularly do this) so install a driver - reboot - check to be sure it is installed and repeat as

needed.

Repeat at Device Makers - BTW at Device Makers DO NOT RUN THEIR SCANNER - check

manually by model.

Manually look at manufacturer's sites for drivers - and Device Maker's sites.

http://www.sevenforums.com/tutorials/43216-installing-updating-drivers-7-a.html

If you update drivers manually then it is a good idea to disable Driver Installations in Windows

Updates, this leaves Windows Updates ON however it will not install drivers which will usually be

older and cause issues. If Updates suggests a new driver then HIDE it (Right Click on it) and then

go look for new ones manually if you wish.

Look in the Event Viewer to see if anything is reported about those.

MyEventViewer - Free - a simple alternative to the standard event viewer of Windows.TIP - Options - Advanced Filter allows you to see a time frame instead of the whole file.

http://www.nirsoft.net/utils/my\_event\_viewer.html

Here are some methods to possibly fix the blue screen issue. If you could give the Blue Screen

info that would help. Such as the BCC and the other 4 entries on the lower left. And any other

error information such as STOP codes and info such as IRQL_NOT_LESS_OR_EQUAL or

PAGE_FAULT_IN_NONPAGED_AREA and similar messages.

As examples :

BCCode: 116

BCP1: 87BC9510

BCP2: 8C013D80

BCP3: 00000000

BCP4: 00000002

or in this format :

Stop: 0x00000000 (oxoooooooo oxoooooooo oxooooooooo oxoooooooo)

Many BlueScreens are caused by old or corrupted drivers, especially video drivers however

there are other causes.

You can do these in Safe Mode if needed or from Command Prompt from Vista DVD or

Recovery Options if your system has that installed by the maker.

Memory tests do not catch all errors such as mismatched memory (possible even for sticks

that appear to be identical) and when faster memory is placed in system behind slower memory.

So it is best to also swap sticks in and out to check for those even if all memory tests fail to show

a problem.

To test RAM check here - let it run 4+ hours or so. <-- best methodwww.memtest.org
