Q: Blue Screen error - BCCode: d1 Windows 7 64-bit Ultimate

Any help with this error would be greatly appreciated!

The .dmp file for this error is on my SkyDrive and can be found here:

http://cid-d16317d81ed7816e.office.live.com/self.aspx/Public/dump%5E_files/011211-20623-01.dmp

 

The bugcheck was: 0x000000d1 (0x0000000000000008, 0x0000000000000002, 0x0000000000000000, 0xfffff8800c897f5c)

Answer

A:

Hi,

Results verified with WinDBG, DumpCHK, and BlueScreenView.

There were two 1-21-2011 Bug_Checks in the two minidumps - D1 0x000000D1 and 50  0x00000050.

The CAUSE of the 50 Bug_Check is shown as MEMORY in WinDBG. See memory testing methods in
the troubleshooter and in the next message.

IMAGE_NAME:  memory_corruption
FAILURE_BUCKET_ID:  X64_0x50_nt!MiOutPageSingleKernelStack+f0

------------------------------------------

The CAUSE of the D1 Bug_Check is shown by all 3 debuggers as NETw5s64.sys which is the Intel WiFi
driver. If it is a built-in device check the System Maker and  then Intel Downloads for updated drivers.
If a separate WiFi device check with its maker and then Intel Downloads for updated drivers. See
driver update methods in the troubleshooter and in the next message.

IMAGE_NAME:  NETw5s64.sys
FAILURE_BUCKET_ID:  X64_0xD1_NETw5s64+10f5c

When you see a Windows component indicated as CAUSE it means something else drove it into fault.

References to Vista also apply to Windows 7.

Have you added any hardware lately? Have you updated any driver just before these started? (Check
Control Panel - Windows Updates to see if any drivers were updated there about the time this started)
Main likely culprits are Video driver, other major drivers, memory, and antivirus/antispyware/security
products could be at fault as well as drive issues.

Use the troubleshooter below and refer to the next message for drivers and memory when you get to
those sections and then return back to the troubleshooter as needed.


BCCode: 50     0x00000050

Cause

The BCCode 50 usually occurs after the installation of faulty hardware or in the event of failure of installed
hardware (usually related to defective RAM, be it main memory, L2 RAM cache, or video RAM).

Another common cause is the installation of a faulty system service.

Antivirus software can also trigger this error, as can a corrupted NTFS volume.

Resolving the Problem

Resolving a faulty hardware problem: If hardware has been added to the system recently, remove it to see
if the error recurs. If existing hardware has failed, remove or replace the faulty component. You should run
hardware diagnostics supplied by the system manufacturer. For details on these procedures, see the owner's
manual for your computer.

Resolving a faulty system service problem: Disable the service and confirm that this resolves the error. If so,
contact the manufacturer of the system service about a possible update. If the error occurs during system
startup, restart your computer, and press F8 at the character-mode menu that displays the operating system
choices. At the resulting Windows Advanced Options menu, choose theLast Known Good Configuration
option. This option is most effective when only one driver or service is added at a time.

Resolving an antivirus software problem: Disable the program and confirm that this resolves the error. If it
does, contact the manufacturer of the program about a possible update.

Resolving a corrupted NTFS volume problem: Run Chkdsk /f /r to detect and repair disk errors. You must
restart the system before the disk scan begins on a system partition. If the hard disk is SCSI, check for
problems between the SCSI controller and the disk.

Finally, check the System Log in Event Viewer for additional error messages that might help pinpoint the
device or driver that is causing the error. Disabling memory caching of the BIOS might also resolve it.

--------------------------------------------------

Think Video drivers mainly though it can be others. See the driver section in my generic bluescreen
troubleshooting methods below. BIOS, low level chipset drivers and antivirus/antispyway/security
programs can also cause this. Check the troubleshooter and when you get to the driver and memory testing sections refer to the generic methods in next message and then return to the troubleshooter
if needed.


Cause

A driver tried to access an address that is pageable (or that is completely invalid) while the IRQL was too high.

This bug check is usually caused by drivers that have used improper addresses.

If the first parameter has the same value as the fourth parameter, and the third parameter indicates an execute operation, this bug check was likely caused by a driver that was trying to execute code when the code itself was paged out. Possible causes for the page fault include the following:

  • The function was marked as pageable and was running at an elevated IRQL (which includes obtaining a lock).
  • The function call was made to a function in another driver, and that driver was unloaded.
  • The function was called by using a function pointer that was an invalid pointer.

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.

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)
tcpip.sys - Address 0x00000000 base at 0x000000000 DateStamp 0x000000000


This is an excellent tool for posting Blue Screen Error Information

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.

The log might give you the answer if there was a corrupted driver. (Does not tell all the possible

Also run CheckDisk so we can rule out corruption as much as possible.
