What is Error iaStorA.sys?

IaStorA.sys is basically a driver file and is found under the C:\Windows\System32\drivers folder. This driver works in line with Intel Rapid Storage Technology and allows communication between your PC and hardware or other connected devices. 

What does Intel Rapid Storage technology do?

Intel Rapid Storage Technology is a Windows-based application and it runs to improve the overall performance and reliability of your Windows PC. This technology is in general equipped with SATA disks for desktop, mobile, or other server platforms. 

BSOD errors are one of the most painful things for Windows users and it is our bad luck that even the new Windows 11 is prone to these. The iaStorA.sys is one such BSOD error that is now being encountered by Windows 11 users too. BSOD errors are indications that your PC has encountered a fatal system error that can be due to software crashes or some kind of hardware fault. Talking specifically about the iaStorA.sys BSOD error, it comes with two kinds of error messages:

• DRIVER_IRQL_NOT_LESS_OR_EQUAL (iaStorA.sys) or
• SYSTEM_SERVICE_EXCEPTION (iaStorA.sys).

If you’re not aware of that then let me tell you that these errors point towards Intel Rapid Storage Technology (IRST) which is a driver file that helps to improve the performance and reliability of your SATA Disk-driven PC.

If you are also fed up with frequent encounters with this BSoD error here in this fixing guide I am going to share various ways to fix it. The methods described in this guide are also applicable to Windows 10 hence if you are encountering iaStorA.sys BSOD on Windows 10 this guide will be helpful for you as well.

As I have already told you that this error is related to some kind of issue with the Intel Rapid Storage Technology (IRST). But besides this, there can be other reasons too. For instance, there can be some unwanted background process running on the PC, any third-party app conflicting with the system, or maybe a corrupted Windows system file.

Based on this, here are the possible solutions to fix the iaStorA.sys BSOD error.

1. Close Background Services and Update your Windows

With the belief that there are some unusual and unnecessary background services running on your PC, stopping them can definitely help. Here’s how to do it.

1. Press Win + R to open the Run dialog box. Now enter msconfig and click OK.

2. This will open the System Configuration window on your PC. Switch to the Services tab and checkmark the Hide all Microfot Services option.

3. Now click on Disable all button and click on OK.

4. Next, search and open Settings and go Windows Update.

5. Click on the Check for Update button and if there is any pending update available, install it by following the on-screen instructions.

6. Finally, Restart your PC.

2. Reinstall Intel Rapid Storage Technology (IRST) Drivers

There can be some issues with the current IRST drivers installed on your PC. Hence removing and fresh installing the drives can solve the issue. Here’s the procedure to do so.

1. Search and open Device Manager.

2. Expand the IDE ATA/ATAPI controller section, right-click on the driver, and click on Uninstall device.

3. Uncheck the Delete the driver software for this device option and click on the Uninstall button. If there are multiple drivers listed under the IDE ATA/ATAPI controller section, make sure to uninstall all of them using the same procedure.

4. Restart your PC and again open the Device Manager.

5. Make sure our PC is connected to the internet and click on the Scan for hardware changes option in the Device Manager window. This will make Windows look for drivers on the next boot and install them automatically.

3. Update Intel Rapid Storage Technology (IRST) drivers

Since the issue is related to the Intel Rapid Storage Technology, updating its drivers is definitely a best practice to stay away from software-related glitches. Here’s how can update the IRST drivers.

1. Open a web browser like Google Chrome or Microsoft Edge and head over to the Intel IRST webpage.

2. From the version drop-down menu, select the latest version of IRST.

3. Now scroll down to the Available Downloads section and click on the download button saying Download setuprst.exe

4. Accept the terms to begin the downloading of the drivers.

5. Once downloaded, open the downloaded setuprst.exe file and install the drivers by following the on-screen instructions.

6. Finally, restart your PC.

4. Remove the Windows.old folder

When Windows receives a big system update, it automatically creates a folder with the name Windows.old, containing the files of the old Windows OS.

While this is to make sure you don’t lose any data, if there is any bug or corrupted file in there, it can cause the iaStorA.sys BSOD issue. Hence you should delete that folder.

Here are the steps.

1. Search and open Command Prompt as administrator.

2. Now execute the following commands in Command Prompt one by one:

3. Executing the above commands will delete Windows.old folder from your PC. Now just perform a restart of your PC and see if the issue is fixed.

5. Remove Suspicious 3rd-Party Apps

There can be some 3rd-party apps that are installed on your PC and are in conflict with the IRST drivers or the rest of the Windows OS. If you have a suspicion about any of the apps or if there is an app that is not from a reliable source, then you can try uninstalling that.

1. Open Settings by pressing Win + I on the keyboard.

2. Now go to Apps > Apps & features.

4. Scroll down and click on the three-dot menu next to the app that is under suspension and select Uninstall. Here I have demonstrated the step with the example of the NOX app.

5. Click on Uninstall again for final confirmation and follow the on-screen instructions to uninstall the app completely.

6. Finally, restart the PC.

6. Revert Back to the Previous Windows Restore Point

If you were not able to fix the iaStoreA.sys BSOD error then you should try rolling back to the previous Windows restore point where there was no such BSOD issue. But please note that this fix is only applicable to those Windows users who have previously created a System Restore Point.

1. Search and open the Create a Restore Point option.

2. Thsi will open the Switch to the System Properties Window. Switch to System Protection tab and click on the System Restore… button.

3. You will now be on the System Restore window. Click on Choose a different restore point option and hit on Next. You can also select the Recommended Restore if you want.

4. Now select the Restore Point and click on the Scan for affected programs button in order to detect the corrupt files on your system.

5. Again click on Next.

6. Finally, click on Finish and restart your PC.

7. Reset your Windows PC

Finally, if nothing works, the last try that you do is reset your Windows PC. This will delete the system files and folder and hence it is advised to back up your data.

Resetting the PC will restore all the system files, applications, and settings to their default state. Here’s how to reset Windows 11.

1. Open Windows Settings. You can press Win + I on your keyboard.

2. Now go to System > Recovery.

3. Under the Recovery options section click on the Reset PC button.

4. On the Reset this PC window, choose either of the options. I would advise you to select the Keep my files option to prevent the data loss.

5. Now, follow the on-screen instructions to complete the resetting process.

Here comes the end of this fixing guide and I am hoping that you have fixed the iaStorA.sys BSOD error on your Windows PC. This is definitely a quite frustrating error like any other BSoD error but it should be gone with simple fixes like updating or re-installing the IRST drivers.

But if not, you should bring your attention to the 3rd-party apps and also look for pending Windows updates. Lastly, if nothing works, then you can either restore to a previous System Restore Point, reset the PC or can perform a clean re-install of the Windows OS.
