APC_Index_Mismatch (Dell Inspiron)

Sam Mihyar · 12 Sep 2018

Greetings,

I searched this issue before posting and I couldn't find it, so here we are.

Computer errors isn't my area of expertise, but I tried all solutions I could find online (Even formatting and reinstalling the Windows) but to no avail, so I come to your aid.

My problem is this: I was sitting on my 3year laptop browsing youtube when all of a sudden the WiFi icon in the bottom right corner disconnected from my home network and became a Red Cross instead. I couldn't connect or search for any network. However, I could still connect my ethernet cable and connect to the internet. Anyways, tried updating the network adapter wireless driver but didn't work. I was frustrated so I formatted the laptop, downloaded Win8 and installed the drivers (They weren't installed for some reason when I downloaded Win8). The Wifi started working again, but when I would launch a certain game client (Battle.net from Blizzard), the laptop would count down a restart siting (APC_Index_Mismatch) as the reason.

Tried all sorts of things until I decided to format again and revert back to Win7. Did that, downloaded drivers and the WiFi worked again nicely, but the Index mismatch persisted. I've tried uninstalling/reinstalling drivers, updating them, deleting Realtek (Some forums suggested that was the issue), etc...

I cannot fix this at all, and I need professional (Your) help :)

I have attached the file I should be linking, but let me know if you require any other information or logs from me.

What things more specifically?
I don't see any dumps in your attached files.
Please peruse: Dump Files - Configure Windows to Create on BSOD - Windows 7 Help
Enable small memory dump (Minidump)

Now enable and run

Diagnostic Test
DRIVER VERIFIER

Warning
Please make a backup of your important files and get your rescue media or create one.
Please create a restore point.

Please follow this tutorial to run driver verifier.

Driver verifier stresses your drivers and will crash your pc if any driver fails due to a violation.

Driver verifier should be performed for a max of 48 hours, or when you have a bluescreen, whatever comes first.

If driver verifier has found a violation and you can't get back into windows normally, try to boot into safe mode and reset in safe mode driver verifier, or in the troubleshooting options open command prompt and type verifier /reset.

Note
Your system will act very sluggishly while driver verifier is enabled, this is normal as your drivers will be being subjected to heavy testing in order to make them crash.

I tried uninstalling/installing network adapter/sound drivers. Tried updating them, tried to do windows updates for the .NET framework. Tried disabling Realtek and updating it. I know this might be nothing to you with experience, but like I said, this isn't my strong-suit!

Anyways, I will be generating the DMP files you require and submitting them ASAP.

Thank you for your reply :)

I hope I did this correctly. I read the tutorial, activated a minidump using method #1, then went on to activate the verifier.exe, restarted the computer, triggered a bluescreen crash, then linked the minidump file.

Apologies if I'm missing something, let me know.

P.S. Should I log more crashes in the minidump or one would suffice?
