Why am I getting this Blue Screen? BCCode: d1

Hi,

As OEM Toshiba is responsible for the proper operation of BOTH the hardware and
Windows.

Since the issue started on the first day with the new laptop you should contaxt Toshiba
Support, check their on-line documentation and drivers, and ask in their forums about
any known issues with that model. Keep in mind that the more you do the more they
will say it is something you have done. Added that even if you were somehow able to
resolve the issue you would still want it documented in case there are further related
problems down the road.

===============================================================

If you really want to troubleshoot the issue (which I don't recommend on a new system) :

The Bug_Check was D1 CAUSE athrx.sys Atheros Extensible Wireless LAN device driver.

BugCheck D1, {18, 2, 1, fffff88004259d16}
Probably caused by : athrx.sys ( athrx+18d16 )

IMAGE_NAME:  athrx.sys
FAILURE_BUCKET_ID:  X64_0xD1_athrx+18d16
BUCKET_ID:  X64_0xD1_athrx+18d16

athrx.sys dated 9/26/2010 Atheros Extensible Wireless LAN device driver.

fffff880`04241000 fffff880`043c6000   athrx    T (no symbols)          
    Loaded symbol image file: athrx.sys
    Image path: \SystemRoot\system32\DRIVERS\athrx.sys
    Image name: athrx.sys

1. Check with Toshiba for updated Atheros drivers and then check Atheros to see if there
are even newer ones. Install any from Toshiba first so those will be the rollbacks in case
of any issues with the ones from Atheros.

Atheros WiFi Drivers.

2. Check Toshiba for updates to the BIOS, low level chipset drivers, and the major on-board
and separate device drivers. Run DriverView - set VIEW to Hide Microsoft drivers - update
those without Dump in their names (see driver update methods in the next message).

3. Use the other methods in the troubleshooters below and in the next message.

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.

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.

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

Often updating drivers will help, usually Video, Sound, Network Card  (NIC), WiFi, 3rd party
