Stop code APC_INDEX_MISMATCH

Hi,

The error you've encounter usually appears when a new hardware was installed on the computer. It could be a USB device that is newly installed. It's recommended that you install and update the device's drivers.

For you to update the driver manually, follow the steps below:

1. Right-click on the Windows key.
2. Click Device Manager.
3. Locate and expand the category where the new device belong.
4. Right-click the device’s name from the list and click Update Driver Software.

If the above steps did not resolve the issue, we suggest that you follow the instructions given to troubleshoot blue screen errors found in this article.

For more information regarding the error, refer to this article: Bug Check 0x1: APC_INDEX_MISMATCH.

Let us know if you need further assistance.

Hi,

ntoskrnl.exe & ntdll.sys are Windows components which means something else drove them into Fault.

Since the computer is new and still under warranty please contact Lenovo Support and the seller. As OEM Lenovo is responsible for the proper operation of both the hardware and Windows. So regardless of the cause it is theirs to resolve. And the unit is under full warranty and may be in need of repairs or replacement. Added that even if you are able to resolve the issue you would want it fully documented just in case there are related problems down the road. Remember the more you do the more they will say it is something you have done.

We can analyze the minidumps if you make them available from the OneDriveor other file sharing sites (such as MediaFire). If you have problems uploading

the minidumps copy them to the Desktop or the Documents folder and upload

them from there.

The most common cause of this Bug_Check is drivers so use the methods below to update the BIOS and major drivers. If needed we can tell you how to run Driver Verifier however with Windows 10 its a good idea to update all the major ones as the maturation process is still in the early stages. (See how to update drivers and run Driver Verifier below.)

BCCode: 01    0x00000001  <-- read this linkhttp://www.faultwire.com/solutions-fatal\_error/APC-INDEX-MISMATCH-0x00000001-\*1016.html

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

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

Run DriverView - set VIEW to Hide Microsoft drivers - update those without

Dump in their names (and update BIOS and chipset drivers).

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 -

heck manually by model.

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

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

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

For the Windows Memory Diagnostic Tool.

Type in Cortana's search box ->  Windows Memory Diagnostics 

at top of list - click it. in Windows 8/8.1/10 the name is "Windows MemoryDiagnostic".

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

After doing ALL the updates you can, and if the issue continues, then run

DriverVerifier. 

Driver Verifier can help find some BSOD issues :

WINKEY + X - RUN - type in -> verifier /reset      hit enter to disable

Use BlueScreenView to see if there is a driver specified in the error message.

Also check with MyEventViewer at the time of the BlueScreen.

If DriverVerifier creates a minidump upload it and post the link here so we can

analyze it.

Hope this helps.
