Windows 10: Computer lagging and latency issues

Hi everyone,


I'm going to preface this by saying I know enough about technology for the easy day to day problems but I am in over my head with this one.


Over the past few days, I've been struggling with my laptop practically brand new, maybe two months old? lagging and freezing constantly. At first I was noticing that System Interrupts was taking up a significant amount of my CPU sometimes up to 50% and the computer was extremely slow until it worked itself out. I tried doing a little research and did some of the troubleshooting mentioned in the articles I found. I tried restarting my computer, I ran Windows for updates and updated which actually seemed to make the problem a little worse. Then I checked the disk for errors and nothing out of the ordinary came back.


I checked in with my dad who is much better with technology than I am but is unfortunately is 2.5 hours away and can't help em out physically told me to run a latency check. After running it about ten minutes, it came up with problems. And all I am doing is using my computer for the internet, powerpoint, word, etc. when it's happening. I'm not sure what I need to post but below are the results are what I received when I ran LatencyMon.

CONCLUSION

_________________________________________________________________________________________________________

Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.

LatencyMon has been analyzing your system for 0:10:53 h:mm:ss on all processors.

MEASURED INTERRUPT TO USER PROCESS LATENCIES

_________________________________________________________________________________________________________

The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.



Highest measured interrupt to process latency µs: 3613.60

Average measured interrupt to process latency µs: 11.340870



Highest measured interrupt to DPC latency µs: 3607.50

Average measured interrupt to DPC latency µs: 4.850457





_________________________________________________________________________________________________________

REPORTED ISRs

_________________________________________________________________________________________________________

Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.

Driver with highest ISR routine execution time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation



Highest reported total ISR routine time %: 0.043671

Driver with highest ISR total time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation



Total time spent in ISRs % 0.044479



ISR count execution time <250 µs: 106962

ISR count execution time 250-500 µs: 0

ISR count execution time 500-1000 µs: 12

ISR count execution time 1000-2000 µs: 0

ISR count execution time 2000-4000 µs: 0

ISR count execution time >=4000 µs: 0





_________________________________________________________________________________________________________

REPORTED DPCs

_________________________________________________________________________________________________________

DPC routines are part of the interrupt servicing dispatch mechanism and disable the possibility for a process to utilize the CPU while it is interrupted until the DPC has finished execution.



Highest DPC routine execution time µs: 11536.014644

Driver with highest DPC routine execution time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation



Highest reported total DPC routine time %: 0.176341

Driver with highest DPC total execution time: ndis.sys - Network Driver Interface Specification NDIS, Microsoft Corporation



Total time spent in DPCs % 0.636885



DPC count execution time <250 µs: 683352

DPC count execution time 250-500 µs: 0

DPC count execution time 500-10000 µs: 6315

DPC count execution time 1000-2000 µs: 7

DPC count execution time 2000-4000 µs: 4

DPC count execution time >=4000 µs: 2





_________________________________________________________________________________________________________

REPORTED HARD PAGEFAULTS

_________________________________________________________________________________________________________

Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.



NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.



Process with highest pagefault count: tiworker.exe



Total number of hard pagefaults 57055

Hard pagefault count of hardest hit process: 10685

Number of processes hit: 121

I can see there is a problem particularly with the Kernel Mode Driver and the DirectX Kernel. I just have no idea what to do about. I've tried googling but I'm just afraid to do anything that will ruin my computer or prevent it from working. Any help or tips would be greatly appreciated! As a teacher and getting into the school year, I need a working computer. Thank you!

I'm having severe issues with DPC latency issues. Problem may be power and internet related. Any help?

Hi Parker,



Thank you for writing to Microsoft Community Forums.



I thank you for sharing the information about the device. I also appreciate your effort to narrow down the issue.



Here are the few steps you can try.

1. Click Start and select Settings >
   System > Power & sleep.
   
2. Click on Power Options.
   
3. Click Change Plan Settings next to the selected Plan.
   
4. Click Change Advanced Power Settings.
   
5. Scroll down to and expand Wireless Adapter Setting and
   Power Savings Mode.
   
6. Change on Battery and Plugged In to 'Maximum Performance'.
   
7. Click Apply and OK. Restart the computer and test your latency.
   
   
   

Please refer the article from HP on Improving Latency and Reducing Lag.



Addition to the previous suggestions, please download the latest motherboard and network adapter drivers, also upgrade the BIOS by contacting the computer manufacturer. For more information
I suggest you contact the computer manufacturer support.



Note: Modifying BIOS/ complementary metal oxide semiconductor (CMOS) settings incorrectly can cause serious problems that may prevent your computer from booting properly. Microsoft cannot guarantee that any problems
resulting from the configuring of BIOS/CMOS settings can be solved. Modifications of the settings are at your own risk.








Hope it helps.
