Sys Interrupts extremely high despite exhaustive effort to remedy

Recently picked up an HP Laptop, model HP 15-f233wm, it's one of several I keep around for random tasks. This machine is spec'd out as follows:

* Intel Celeron N3050 @ 1.6GHz
* 4GB 1x4GB DDR3L SDRAM
* Intel HD Graphics 620
* Zheino 256GB SSD S3 2.5" SATA3 3D Nand SSD
* Realtek Ethernet and Wireless

When I first picked up the machine I dropped a brand new SSD into it and performed a fresh installation of Windows 10 Home using the Microsoft provided media creator image. Everything went well, nothing seemed amiss during the installation.

Shortly after getting the machine updated, maybe a day of light use, I noticed latency issues and chopping in the display during streaming playback, but Warcraft seemed to run just fine, which led me to the task manager where I noticed the system interrupts were running between 15 and 30 percent.

Rebooting, stripping services, tearing down the machine and making sure there were no ground faults or misaligned connectors, a complete reinstall, switching to a standard HDD, changing the memory, wireless card, and removing the optical drive all had no impact on the overall issue, which is that one out of every five starts, the system interrupts are through the roof.

Booting from a live Linux installation, and/or installing Linux to the machine seemed to work fine, I didn't experience the issue while running various versions of Linux, and have been unable to track down the fault in Windows.

Event logs show only DCOM errors and the occasional complaint about a Kernel PnP failure, device manager shows all devices properly installed, and the updates have all been applied, I even installed and ran the HP Support Assistant (blah), and installed their recommended packages with no change in the situation.

I'm not a Windows 10 expert, coming from the Windows 2000 era and mostly using Linux for everything except games now, I am not sure where to go from here.

If there anything I am missing, or is this issue simply not fixable?

Thank you for the reference, I plan to spend a few hours later goofing with it I'll update progress in the morning.

Thank you for the article, it provided me with the tools I needed to hopefully resolve this issue.

I installed Latency Monitor, and found that my storport.sys had extremely high DPC counts. A Google search led me to this article here....

Storport.sys has severe DPC latency causing audio to stutter and drop out


There's a ton of information here but after digesting it all I ended up with the following solution....

I opened an administrative PowerShell and executed these commands....

Code:

sfc /scannow
dism /online /cleanup-image /restorehealth
powercfg -h off

After a reboot, the system has been operational all night and most of the morning with a Sys Interrupt of less than 1% spiking to 3-5% under load.

The sfc came back with no errors, the DISM operation assuredly repaired any errors there, and turning off the hibernation seems to have settled things down.

Thanks again for the assistance, I hope I can contribute in the future.
