IAStorUI error - PCIe SSD is offline

HP Recommended
HP Envy 750-624
Microsoft Windows 10 (64-bit)


I get an error notification every time I restart the computer (and maybe it pops up at other times, too) - in the notification area.


This is a brand new HP (refurbished), Windows 10 computer. Best Buy did a set up and removed bloatware.

I downloaded to latest driver for the IAStor just to be sure, reinstalled it and restarted the computer - no change.



I had read one thread that said the IAStorUI error could be due to improper 'uninstall 'of things, (items left behind in registry, etc) so I thought maybe they caused this when deleting bloatware.


I ran CCleaner to clean up the registry but the error is still there.


When I click on help and it shows that the PCIe SSD is offline it implies that clearing the Metadata might help but says to back it up first.


Since I have no idea what may be in the metadat, I am a little afraid to just click yes.


And, I am brand new to Windows 10 ( had 7 before) so I have no idea how I would back it up.


I believe this SSD and associated software is meant to speed up performance (or maybe just booting?) which is one reason I bought this computer.


Any ideas on how to fix this?

Welcome to the HP Forums 🙂 

I would like to take a moment and thank you for using this forum, it is a great place to find answers. 


As I understand there's an error message every time you restart the device,

No worries, as I'll be glad to help you, that said, I'll need a few more details to dissect your concern & provide an accurate solution: 

Have you attempted to update the Intel storage devices and the BIOS?


While you respond to that, here's what you need to know:

Enter safe mode:

  1. Restart your PC. When you get to the sign-in screen, hold the Shift key down while you select Power > Restart. 

  2. After your PC restarts to the Choose an option screen, select Troubleshoot > Advanced options > Startup Settings > Restart. 

  3. After your PC restarts, you'll see a list of options > select 5 or F5 for Safe Mode with Networking. 

iastorUI error = Intel Matrix Storage Manager driver - See System/Motherboard Maker and the chipset maker.  


This driver could have been driven to a fault by other programs such as Symantec/Norton. 


Check the Intel Downloads in case you don't find the drivers on the official HP website:


Intel Downloads 


Intel Matrix Storage Manager - be sure to check for DATE and set for version of Windows and chipset 


Keep me posted,

If the information I've provided was helpful,

I finally have a few minutes to deal with this. 

I have the most current driver. 


This is a brand new computer set up by Best Buy - it came with windows 10 (and they installed McAfee ).

I'm not sure why I should need to go through all the hassle to update the bios on a new computer. This problem has been there since day 1 (this Feb )


This is what I am reading - "The Intel® Rapid Storage Technology application allows you to optimize and maintain a healthy storage system by creating volumes, customizing performance settings and managing storage system elements. "  As I read further in the Help document it almost sounds like creating volumes, etc is something you do automatically. 


In other words that this is not something that speeds up/optimizes  your computer in the background. If this is true, I doubt I will ever use it anywa. If it is downgrading the computer performance becuase it has whatever this current issue is, then I'm more interested in fixing the problem. 


Under "manage Disk" it says the status is offline and has a link to 'clear metadata'. I don't know what that would do so I haven't done it. But maybe I should try it??

It looks like you were interacting with Riddle_Decipher, but he is out for the day. I'm KrazyToad & I'm at your service. 


I suggest you check for any BIOS update for your HP Envy 750-624.


Also check for any latest updates using the HP Support Assistant.


Download Link:


  1. Click My devices on the top of the HP Support Assistant window, and then click Updates in the window for your device.

    Figure : Updates in the My PC box

    The Updates window opens.

  2. If HP Support Assistant detects updates, a list of updates displays in the Updates available window.

    Figure : Updates window

     Updates window
  3. To check for recent updates, click Check for updates and messages.

    HP Support Assistant connects to the HP servers and performs the following actions:

    • Downloads messages and updates

    • Gathers configuration information

    • Analyzes your computer system

    • Prepares an action list

    If HP Support Assistant finds updates, they display in the Updates available window.

    Figure : Updates available window

    Updates available window

If the issue persists, then clear the Metadata and let me know how it goes.


Thank you 🙂

Clearing the meta data using IRST will clear out meta data mismatches between the PCIe caching SSD and the meta data that is stored on the boot drive. Once this is done then you can reenable the caching function by using IRST (performance or status).


The offline issue typically occurs when hardware has been replaced such as the PCIe SSD or the boot drive and hence the mismatch of meta data between the two devices.  There are other conditions that will also cause the offline issue for the PCIe SSD.
