Protect Yourself From Tech Support Scams
Tech support scams are an industry-wide issue where scammers trick you into paying for unnecessary technical support services. You can help protect yourself from scammers by verifying that the contact is a Microsoft Agent or Microsoft Employee
and that the phone number is an official Microsoft global customer service number.
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.
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
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.
Stop error on a Windows Server 2008 R2-based or Windows 7-based computer when the operating
system uses a virtual storport miniport driver to save a dump file or a hibernation file: "0x000000D1" http://support.microsoft.com/kb/2320550
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
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.
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.
