Major Latency Issues

I have been having this strange memory leak for the past few weeks where my system will all of a sudden be incredibly bogged down, and the audio will start to crack and break as I am watching something or gaming. I thought it was a compatibility issue with my onboard sound, but I turned that off and the problem still persists. Today I was reading and I thought I would test my latency, and I found out that the USBport.sys is causing major latency issues in my system. The problem is that no matter where I look nobody has a real solution. Some have said that Windows released a patch for it, but when I tried to install the patch it told me that I already had it on my system..... Additionally, when I restart my computer it is generally fine for a day or two, but then it begins the cycle all over with latency problems.

I could really use some help to figure out why this is happening... I am open to any suggestions from anyone out there who might have some knowledge on this subject. I will try my best to provide any additional information that people may need to help me diagnose this issue completely. I should note that I have done a full virus/malware scan and found no issues. I have also updated all of the drivers on my board to see if that will fix the issue.

Thank you in advance.

Here are some pictures of what I am experiencing.... For the amount of money I spent on this rig this type of latency should not be occurring.

Click to expand...

USBport.sys is a Microsoft Windows driver and suggests the problem may lie with a USB device.

Try unplugging USB device(s) and see how the system responds.

Info - Driver Reference Table - USBPORT.SYS

I tried unplugging everything I possibly could but I am still getting crazy latency from my dxgkrnl.sys.... It is up to 1400 at the moment with almost nothing installed. Should I just completely wipe my system at this point?
 
Can anyone help me with this? I just formatted and I am still getting latency issues. dxgkrnl.sys is doing the same thing after doing a complete wipe of my system.... This is insane... Is it my video card going? I just got it a few months ago.... anyone???
 
I am only really getting the latency from ataport.SYS now.... I have read 20 different forums and nobody seems to have a real answer....
 
Dear,

To properly troubleshoot issues with high/frequent DPCs/IRPs, we require a XPERF trace. Please follow these steps to generate one:

  1. Download Windows Software Development Kit (SDK) for Windows and run the setup.
  2. Select Windows Performance Toolkit feature (all the others can be unchecked) and proceed with the download/installation.
  3. Once the installation finishes, open an elevated Command Prompt by right-clicking on CMD.EXE shortcut in your start menu and selecting Run As Administrator from the context menu.
  4. Type the following command, which will start tracing, in the Command Prompt window you just opened:
    Code: 
    xperf -on PROC_THREAD+LOADER+PROFILE+INTERRUPT+DPC+DRIVERS+POWER+IDLE_STATES -stackwalk Profile -BufferSize 1024 -MinBuffers 256 -MaxBuffers 256 -MaxFile 256 -FileMode Circular
    If you see a yellow warning "xperf: warning: This system is not fully configured for x64 stack tracing" after running the above command, please complete these extra steps (otherwise, proceed to the step #5):
    Read More:
    If you see a red error "xperf: error: NT Kernel Logger: A device attached to the system is not functioning. (0x1f)" after running the above command, please complete these extra steps (otherwise, proceed to the step #5):
    Read More:

    If you see a red error "xperf: error: NT Kernel Logger: Cannot create a file when that file already exists. (0xb7)", please do the following (otherwise, proceed to the step #5):
    Read More:
  5. Perform some activities with your computer for few minutes, making sure the issues you reported are reproduced.
  6. Run the following command, which will stop the tracing, in the command prompt window you already have opened:
    Code: 
    xperf -stop -d C:\CPU.etl
  7. Compress file C:\CPU.etl
  8. Upload the compressed file to a file sharing service (e.g. OneDrive or DropBox).
  9. Share the download link here.
Thank you.
 
Thank you so much, but I have already run into a problem. CMD says that xperf is not recognized as an internal or external command?
 
I have tried installing the Windows 7 version and it is still telling me the same thing... This is a nightmare.
 
Okay I managed to see yellow text and did the next step only nothing happened after I typed out "HKLM\System etc...
 
Okay I didn't get any errors that time.... So now I just do random things on my computer and hope it logs it basically?
 
Sorry I did not respond I was at my graduation all day lol. I did what you said with no issues. Thank you so much for taking time out of your day to help me... Seriously this is such a horrible issue. Anyways, the drivers are installed. What is the next step from here?
