[SOLVED] Random stutters on Windows 10 even web browsing and idle

I got this laptop not too long ago. 2 weeks later I bought it it gives me random stutters even when I am browsing google and online class. I happens in random occasions but it can be very irritating. It only happens in 1-2 seconds and went back to normal. GPU is up to date, so is Windows and everything. I played games like Monster Hunter World and its on average 50-60fps (bcause it capped on 60fps) and I played Battlefield 1 on Max Settings and its butter smooth.
here's my specs;
Ryzen 7 3750H
Nvidia Geforce 1650 4GB
16GB DDR 4 RAM (8GB dual channel)
512GB SSD
120hz display refresh rate
Windows 10 Home

I've made similar thread on Steam but it did not help me. One of them told me to upgrade RAM because I used to have 8GB (4GB dual channel) but I dont think that is the case because I monitored my ram via Task Bar and seems to be normal. But I upgraded my ram anyway to 2x8GB Kingston HyperX RAM but the problem does not resolves so I'm guessing it's not the ram. Not even CPU or GPU.. stays normal.

Any ideas?

Thanks in advanced
 
you apparently have issues with Network and audio drivers. concentrate on fixing that. I think DDU can remove all audio and video drivers in safe mode, then reboot and let windows install drivers. retest system, if that doesn't work then you can go to the manufacturers websites and get different versions of drivers and try them. sometimes the "latest" version of drivers can cause issues so try different versions made for your system of course.

But one ssd only? Means you partitioned it, might be that ~38 gb on D is getting low.

You have btw the latest chipset drivers? Look at the site from the maker since they might alter these a little.

Might want to go for a support ticket at the makers site anyway since you didn't put this together yourself and they should help with fixing this.

Chipset driver, I'm not so sure. But the model of my SSD is an M.2 micron 2200v mtfdhba512tck. Was looking forward on buying 2.5 inch ssd in my next semester tho. But I will try ask from the support and ask for their help. Thanks

Download LatencyMon and post results
_
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. Also one or more ISR 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 0:07:00 (h🇲🇲ss) on all processors.

SYSTEM INFORMATION
_
Computer name: LAPTOP-E6G40ROG
OS version: Windows 10, 10.0, version 1909, build: 18363 (x64)
Hardware: TUF Gaming FX505DT_FX505DT, ASUSTeK COMPUTER INC.
CPU: AuthenticAMD AMD Ryzen 7 3750H with Radeon Vega Mobile Gfx
Logical processors: 8
Processor groups: 1
RAM: 16192 MB total


_
CPU SPEED
_
Reported CPU speed: 2296 MHz

Note: reported execution times may be calculated based on a fixed reported CPU speed. Disable variable speed settings like Intel Speed Step and AMD Cool N Quiet in the BIOS setup for more accurate results.


_
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): 1326.60
Average measured interrupt to process latency (µs): 4.750276

Highest measured interrupt to DPC latency (µs): 1322.30
Average measured interrupt to DPC latency (µs): 1.694765


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

Highest ISR routine execution time (µs): 17253.956882
Driver with highest ISR routine execution time: HDAudBus.sys - High Definition Audio Bus Driver, Microsoft Corporation

Highest reported total ISR routine time (%): 0.012885
Driver with highest ISR total time: HDAudBus.sys - High Definition Audio Bus Driver, Microsoft Corporation

Total time spent in ISRs (%) 0.016659

ISR count (execution time <250 µs): 80182
ISR count (execution time 250-500 µs): 0
ISR count (execution time 500-1000 µs): 2
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): 1315.958624
Driver with highest DPC routine execution time: ndis.sys - Network Driver Interface Specification (NDIS), Microsoft Corporation

Highest reported total DPC routine time (%): 0.068076
Driver with highest DPC total execution time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation

Total time spent in DPCs (%) 0.145849

DPC count (execution time <250 µs): 1227151
DPC count (execution time 250-500 µs): 0
DPC count (execution time 500-10000 µs): 98
DPC count (execution time 1000-2000 µs): 1
DPC count (execution time 2000-4000 µs): 0
DPC count (execution time >=4000 µs): 0


_
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: discord.exe

Total number of hard pagefaults 246
Hard pagefault count of hardest hit process: 97
Number of processes hit: 12

Driver issues and pagefault issues

Your audio drivers are taking up the most time and are the biggest problem no doubt you need to find the right ones that work for you. Video drivers too. Sometimes you have to go back to a previous driver version if the latest ones are causing issues

Network driver is causing lots of issues too. Where did you get these drivers from did you use driver booster or some stupid utility that updates drivers for you because if you did then this is your problem and you will have to install windows again by formatting and installing clean

Will try that eventually, but during the monitoring.. I was just opened one youtube tab and 1 google image tab and paint tool sai 2.. the monitor spikes but theres no like... stutters or frame drops

Audio is up to date from the first place except for WLAN driver so I updated my RealTek WLAN and problem seems to resolved. I've run LatencyMon and everything seems to be normal. Thanks!
