HP590-P0033w - system interrupts after using DVD drive?

[WilliamHolder]

Hi. My Desktop experiences system interrupts (constant 20% CPU)  after using the DVD Drive. This behavior continues even after I have removed the disc. To make it stop I must restart.
The unit is refurbished / recovered and only recently, 5 days ago, put into service. HP Support Assistant suggests some updates mostly to HP Programs and a BIOS update. The only critical update is the Audio Switch. The driver for the DVD drive is listed as an older generic Microsoft driver. Windows update seems to be working fine. I uninstalled McAfee, Wild Tangent, One Drive and some other misc programs.
There is a Warning about Intel Rapid Storage Technology that keeps appearing as a notification. This app indicates there may be an issue with a PCIe SSD on Port 0 / unknown, and "Clear Metadata" is highlighted. Also some verbiage about write-cache buffer flushing.

Any advice on the system interrupt or the Rapid Storage issue would be greatly appreciated. Thanks for reading and have a good day.

Please try these steps.

Go to "C:\Windows\System32\drivers", then find the iaStorA.sys driver and rename it to iaStorA_old.sys

Try the update again.

You can also try a clean boot (Link) if the issue persists

Keep me posted how it goes

Hi. Thank you for taking the time to reply. The DVD Drive / System Interrupt issue has resolved itself after installing all available updates. I am still getting a warning about: PCIe SSD on Controller 1, Port 0; Offline - together with a highlighted "Clear metadata" link. This might be the same issue addressed by you and others here and at this link: https://h30434.www3.hp.com/t5/Desktop-Boot-and-Lockup/IAStorUI-error-PCIe-SSD-is-offline/td-p/663210... However, given the various responses I remain unclear about what the problem is and what is the correct solution. Should note that the specs for this unit suggest a 16 GB PCIe NVMe 3D Xpoint M.2 Solid State drive but no evidence of it in Device Manager. There is also this message: Acceleration using solid state drives: Disabled - I looked inside the machine and the Optane Memory unit is in place. Perhaps this is the problem? Thank you for reviewing this one more time. Baby steps please.

Have you tried all the troubleshooting steps suggested in the Support Community Link you provided?

If the issue persists, I suggest you Reset the Desktop and then redo the updated and let me know if the problem persists

Hi. I wanted to update this post. The system interrupts were related to a specific DVD with material I downloaded from the web. No other DVD that I have used in this drive has produced the same behavior. The warning I was receiving about Intel Rapid Storage Technology did not reappear after I selected the "clear metadata" button on the app. I have yet to enable the Optane memory although this is simple enough and the HP Support site has information on how to do this - if I recall what I read you simply make a selection on the app and restart.
