BSOD APC_INDEX_MISMATCH error 0x00000001

jfranzreb · 01 Feb 2018

Hello,
I have a user that's getting an APC_INDEX_MISMATCH. From when I was working on her computer, it appeared to happen when I would dock and undock her computer. I previously had disabled hardware acceleration to help fix a different issue. I turned this off and thought it fixed it but didn't. It seems to crash when Windows flashes to adjust the resolution and the program to be maximized and not.

All drivers and BIOS are updated. This is a Dell E7470. This was also a fresh build recently and happened shortly after giving her computer back.

Let me know what else I can provide to you.

Thanks,
Jeff

Hi jfranzreb,

Welcome to 7forums.

It looks like the Realtek audio drivers are involved in the crashes.
Update the Realtek audio drivers and let me know how it goes.

Thank you and thanks for the reply. I just updated the audio drivers and asked that the user dock and undock, which is when it seemed to happen most often.

When I hear back I will update you. Cheers.

Keep me posted.

Dangit. Happened again but I did see a reference to spsys.sys on the screen. Let me know if you need another log dump or anything else. Thanks for your help. I can troubleshoot computers but blue screens... these are tough guys.

Need a dump.

jfranzreb · 07 Feb 2018

Attach the minidump file or run the full log file that I attached originally?

**axe0** · 07 Feb 2018

Either will be fine.

jfranzreb · 07 Feb 2018

Here is the minidump.

Which audio device is in use? Realtek or Intel?
If Realtek, disable Intel display audio in device manager.
If Intel, disable Realtek audio in device manager.
