Windows 10: High Latency from storport.sys (Lenovo Ideapad 310-15ISK Windows 10)

Since my last post only got one reply, I'm hoping to get something more this time around.
I currently own a lenovo ideapad 310 15isk laptop with a conexant smartaudio hd sound driver. Anytime I use the computer, the video and audio stutters. I have had this issue for the past month now. At first i thought it was my sound driver, but the problem came back. Then I thought it was my wifi adapter but the stutter returns after a day. Just when I think I've solved this issue, it keeps coming back and it's driving me crazy. I have done all these steps from a thread found in this forum and more:
-Updated Windows 10 to fall Creators Update
-Updated graphics driver
-Updated sound driver
-Updated wireless drivers
-Disabled wifi card and used a USB adaptor instead
-Disabled my page file
-Disabled event log
-Tried a different browser
-Reset Wifi adapter.
-Changed bit depth and sample rate of speakers.

These are all the "solutions" I have tried in my attempt to rid myself of this problem. I don't have BitDefender on my computer, so that's not the root cause.

I recently downloaded latencymon and ran a scan for almost two hours. These are the results:

Hosted Network Supported: No after upgrading to Windows 10 from Windows 8.1

Hi everyone,

I got correct answer from Lenovo forum and here is the link;

Solved: Re: Hosted Network Supported: No Problem for Lenovo 310-15ISK Laptop (ideapad) - Lenovo Community

The documents you are going to use are provided at the bottom part of the web page.

I hope it works for you too.

Thanks

 

no sound

WIndows 10 on Lenovo ideapad 310, updated drivers, can not hear sound from any website

 

First of all, make an image of your disk. Then you can experiment and if needed restore the system back.

High ISR in ACPI.SYS and DPC Watchdog calls may be caused by Nvidia graphics hardware/driver. Try to completely disable this graphics card in BIOS if possible, or in Device Manager, uninstall Nvidia driver and use Intel GPU instead.

 

I only have an Intel(R) HD graphics 520 graphics card on the laptop.

 

bump. If anyone can help me please tell me what to do. This Problem is driving me crazy. I can't do anything on my computer without getting stuttered every second

 

Maybe some modifications are equipped with Intel graphics only... But at Lenovo site is Nvidia graphics driver listed:
laptops and netbooks :: 300 series :: 310 15isk Lenovo PC Support

You have to experiment yourself. (Make an system disk image before.)

- try to install Advanced Configuration and Power Management Interface (ACPI) Driver for Windows 10 from Lenovo site
- try to install Intel Chipset Driver for Windows 10 from Lenovo site

- try to select Microsoft Basic Display Adapter driver instead ot the Intel one installed
- try to install Intel VGA Driver for Windows 10 from Lenovo site
- try to select Standard SATA AHCI Controller driver instead of the Intel one installed
- try to install Intel Rapid Storage Technology Driver for Windows 10 from Lenovo site

- in Control Panel/Power Options, select Maximum/High Performance power plan
- check if you have the latest bios/uefi (flashing it may be a little bit dangerous).

 

bump. I tried all the suggestions you gave me. None seemed to worked. I even reset my pc to factory settings since I didn't have any important data on the computer but the problem still persists. Do you require additional information muchomurka
