iaStorA.sys Bug Check Code 0x1000007e

Date of initial issues:
11/18/2017 11:26:13 AM
Steps taken to resolve, but unsuccessful?:
Running dell system detect to see if any newer drivers are found for the IRST, but none was found. Looking around on Intel's website for the latest driver, but unsuccessful in finding the particular one (typically I can find these quite fast).

Trying to see if a hard reset on the computer would do anything (didn't think it would), but no luck.
Operating System:
Windows 10 64-bit HOME Fall Creators Update (Older Builds Perfectly Fine Without Any Issues)
List current issues or symptoms:
The iaStorA.sys appears to be at fault (I'm thinking its the driver). Caused By Address : iaStorA.sys+5f578. Crash Address : iaStorA.sys+5f473

This happened after I updated my laptop to the latest Windows 10 64-bit Latest Bild Fall Creators Update (Older Builds Perfectly Fine Without Any Issues). The error only happens on startup; however, after the BSOD everything boots up just fine. This only happens when I turn on the computer and not during a restart. I can restart the computer without any BSOD. This happens mainly when I shutdown the computer and turn it on again at a later time (even if its a few minutes later for testing purposes).

I have scanned my computer quite extensively, but if you'd like for me to scan with other tools to just rule out any Malware or anything I'm open to this.
OS Architecture:
The iaStorA.sys Error.txt file was taken through BlueScreen View as I use this as a technician from time to time.

he violation occurred in iaStorA.sys which is the Intel RST (Rapid Storage Technology) driver. Remove and reinstall/update the driver. Which Dell Computer model do you have?

Please navigate to Dell's website and update your IRST driver below.

Hello Jesse L,

Thank you for your reply!

Here is my system configuration: www.dell.com/.../configuration

Computer: Inspiron 17R SE 7720

The configuration hasn't changed at all.

Dell System detect is saying that all of my drivers are up to date.

Here is the small mini dump from one of my tech tools:

If you'd like I can attach the full mini dump as well.

I found this article too: www.dell.com/.../stop-error-in-iastorsys---kb-article---311881

I don't know if the above article would help at all. With this being said, would you like me to progress forward with the uninstall, restart the computer, and reinstall the IRST that is supported for my computer? Is there a newer version that is supported for my computer that Dell doesn't have listed for my make/model?

I appreciate your help!

It looks like the latest for my computer is the following (directly from Dell's website www.dell.com/.../drivers

Intel Rapid Storage Technology Driver Serial ATA 29 Dec 2015

Category: Serial ATA

Importance: Recommended

Version: ,A00

Release Date: 14 Oct 2013

File Name: 5460_Serial-ATA_Driver_NGJJW_WN_12.8.2.1000_A00.EXE

File size: 22.89 MB

Description: This package provides the driver for the Intel Rapid Storage Technology and is supported on the Inspiron 5323/5420/5720/7420/7720, Vostro 3360/5460/5560, XPS L322X running the following Windows operating systems: Windows 8.1.

Being that my computer is running Windows 10 Home 64-bit would this change anything? I believe there may be a version 13 driver out there, but I'm not sure if that or even a newer driver could help. I will most certainly take your recommendation on the uninstall. Would you like for me to follow these steps: answers.microsoft.com/.../e3c4b6d6-56ba-4ac5-be50-89843c9d9b22

Sorry for the double post. I noticed the form is slightly different. All responses must be moderated.

The uninstall, and reinstall didn't do the trick. Do you have any other recommendations Jesse?

Thank you for your help Jesse!
