HP590-P033w - system interrupts after using DVD drive?

[Zshazlez]

I have the same issue and haven't tried this solution yet.  What update are you referring to?  The OP didn't mention an update, just advice on what to do about the issue.  Is your suggestion related to Windows 10 Update 1903?  I have not attempted to run that update, but I'm having the issue of System Interrupts when opening the dvd drive as stated above.  So how does renaming the driver resolve the issue?

[Riddle_Decipher]

@Zshazlez It's the BIOS update he was referring to, that said, the steps are related to the issue with the RST (Rapid Storage Technology), if you don't have the same error, we can start fresh as the OP's post has nothing to do with your concern, except you have issues when the DVD drive is used, perhaps, you can share a screenshot of the error that appears, if its the same error as the OP, please do attempt the steps to rename the file as it seems to have worked on multiple devices, I'll list the steps below for your ease of access:

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

Once done, I suggest you download and run the Windows update troubleshooter from this link and it will automatically fix the Windows update issues: Click here

If the issue persists, uninstall Intel rapid storage and then try updating Windows.

Also, install the HP Support Assistant using the steps on this link to install all relevant updates for your device: Click here

Why would you say the OP's post has nothing to do with my concern.  His original problem is stated as "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."  That is exactly what is going on with mine.

He then lists things that he tried that did not work as well as some other warnings his PC is giving him, such as the RST problem.  Now, mine is not giving me that error.  When I look in "C:\Windows\System32\drivers", there is not a file named "iaStorA.sys" for me to rename.  So those steps don't apply to me.

I am not getting "error" that I can share in a screenshot.  I see the "System Interrupts" process going to about 20% CPU usage as soon as I open the DVD drive.  The OP replied in his thread indicating he did all of the updates suggested by the HP Support Assistant, including the bios update, and the DVD drive problem went away.  I attempted to do the same and have ran all of the WIndows Updates but the problem still persists.  Every time I do run it, it wants me to change my display drivers.  I've tried the "latest", the "suggested", and the "local" (can't remember exactly what the last one was called) and none of those fix the issue.  But no matter which driver version I choose, an update to the driver is suggested next time I run the HP Support Assistant, wanting me to switch to one of the other two versions.

I'm hoping you can tell me what's going on with my DVD drive so that it can stop eating 20% of my CPU.

@Zshazlez I suggest you update the BIOS among other drivers and software using the HP Support Assistant: Click here, if the issue with system interrupts or freezing persists, please follow the below steps:

let's start with performing a hard reset on the PC to release any excessive static/power that could have caused the issue.

• Turn off the computer.
• Disconnect all external connected peripheral devices such as USB storage devices, external displays, and printers.
• Unplug the AC adapter from the computer.
• Press and hold down the Power button for about 15 seconds to drain any residual electrical charge from the capacitors that protect the memory.
• Press the Power button to turn on the computer.
• If a startup menu opens, use the arrow keys to select Start Windows Normally, and then press the Enter key.

Second, you can check if there is Bios update available for your PC, here is the link to download (if HP support assistant didn't do the update)

Perform a hardware test using the below steps:

• Hold the power button for at least five seconds to turn off the computer.
• Turn on the computer and immediately press Esc repeatedly, about once every second. When the menu appears, press the F2 key.
• On the HP PC Hardware Diagnostics (UEFI) main menu, click System Tests.
• Click Extensive Test.
• Click Run once, or Loop until error.
• While the test is running, the time remaining and test result for each component display on the screen.

If a component fails a test, write down the failure ID (24-digit code) for when you respond back to us.

Depending on the test results, If the test passes then I would suggest you perform a complete system recovery. 

Note: Recovery will wipe off everything from the computer. If you have anything important get in touch with some local stores to get your data backed up.

Note: The CPU usage is system managed and cannot be tweaked.

Keep us posted,

Is there someone else that can help me? You are not even reading the posts. Your first reply made it clear you had not read the original post and now you have made it clear that you have not read mine. I already stated that I updated the bios as well as running the HP Support Assistant. And yet that is the first thing you suggest in your reply. Please elevate my case to someone who will give me some attention. There is obviously a problem with the way the DVD drive is communicating with the system that is causing the interrupts and, because of the OP, I know I'm not the only one who has experienced it. A system restore is likely not going to resolve this issue and I am not going to lose everything on my PC because all you do is copy and paste some low-tier help desk suggestions.

[Riddle_Decipher]

@Zshazlez I was under the impression that you had installed windows updates alone as per your words - "I attempted to do the same and have ran all of the WIndows Updates", which is why I suggested updating the BIOS and other drivers as well, that said, If you've already done that and the issue persists, you may want to do a hard reset (no data would be lost) followed by the hardware test using the updated set of steps in my previous post, once you reply with the results, we can work on a more accurate solution.

And I would like to reiterate that the CPU usage cannot be changed, it's system managed, what we could do, is work on refreshing the system settings if the hardware tests pass.

I haven't suggested a system restore anywhere in the post, I'm not sure where you got that from, but I understand this isn't easy and I'm here to help, we can get through this situation with a little co-operation.

I did the extensive test but everything passed. I did some more troubleshooting and I found that if I right-click on the DVD drive in File Explorer, it opens with out causing System Interrupts to jump to 20%. But, if I use the button on the drive itself, System Interrupts does go to 20%. So that leads me back to thinking it's a hardware or driver issue. Any thoughts? Is there another driver other than the generic Windows one?

[Riddle_Decipher]

@Zshazlez The fact that all tests have passed, confirms that this isn't a hardware issue, that said, It seems like you might not have the right CD/DVD driver. If you remove from Device Manager and reboot, Windows will install a new one.
Also, if that doesn't work, please create a new user account and check if that works fine: click here for steps.

If the issue persists, please back up all important data & perform a system reset using the steps here.

[Zshazlez]

I've done that already. It uses the generic Windows cdrom driver. The OP noted the same thing. If I remove it from Device Manager and reboot, I get the same generic driver. Any idea what the driver should be?

[Riddle_Decipher]

@Zshazlez It is the generic driver, however, if the existing driver is malfunctioning or is corrupt, reinstalling it by removing and restarting the computer, should fix the issue,

That said, if that doesn't help, please create a new user account followed by resetting windows as suggested earlier to resolve the issue and let me know how that goes.
