CPU spikes and performance lag

Hi everyone. During the past few days I have a problem regarding my computer performance.

Problem:
-My computer is getting random performance lags that last 3-5 seconds.
-The cpu usage will jump when it happens; anywhere from 50-100%.
-Large Ethernet spikes as well.
-It's completely random and is very hard to catch but it happens when I'm:
a. browsing the internet ; engaging in miniscule internet activities.
b. opening an application on my computer.
c. watching a video, both on and outside the internet.
d. playing a software intensive game.

symptoms:
-Computer slows but doesn't freeze
-the really bad spikes are up to 100% cpu usage; usually though they are 50-80%.
-Video sound gets distorted and choppy; like if you have an injured CD that still plays right through the scratches but gets all choppy sounding.
-often times the mouse pointer will, all of the sudden, be trailing during the strange slow motion performance lag.

I had the same problem for like a week and it all of a sudden got fixed without me doing anything. However after 3-4 days the problem returned.

Do you have any ideas for a solution. I scanned my computer with Avast Security and it found no viruses on my computer.

My specs:
- Windows 10 build 14393
- Nvidia GeForce GTX 960
- Driver version 375.50
- Intel Core i5-6600 CPU @ 3.50 GHz

I have the same problem and followed all steps mentioned by tairiku and I must say it is a bit better but system keeps garbling up sound when playing heavy load games on win10

I bought a asus xonar DS pci soundcard and problem remains though a bit less then onboard sound.

Any help please?

Regards,
Vince

The best thing is to get a performance trace when the CPU spikes and lag are happening. Fortunately, Windows 10 has a tracing tool built-in, called Windows Performance Recorder.

When you notice performance has degraded, open an administrator powershell prompt and type:

Code:

wpr.exe -start GeneralProfile

Wait 2-3 minutes (or less), then type in the same prompt:

Code:

wpr.exe -Stop $home\Desktop\profile.etl

This will place a file called "profile.etl" on your Desktop.

Upload the profile.etl to Onedrive/Google Drive/<insert file host> and post a link to it here.

Hello everyone, I have a Toshiba Satellite (9A420864K), Running Windows 10 Home. I am having huge lag spikes and a buzzing sound coming from my speakers. I've literally tried everything. Currently happening, Disk 100%.
Things I have tried--------
Disabling SuperFetch, Uninstalling Audio Drivers, Running Programs that's supposedly worked for others, Every link/video I have went to has not worked period, FINALLY Fresh Install big negative as well.
I have thought about buying a new fan for it not exactly sure if I need to, Don't want to spend money if there is an actual fix for this issue. Not a lose screw...Not bouncing around like a monkey trying to get it to buzz, but I am running around the big web trying to find some type of relief. Also my internet is extremely slow, I have 60mb/s, currently a nasty 350-410kb/s.
