Windows 10: lagging

my computer hangs too much when I start the windows …...but sometimes whenever I restart it starts performing better then it lags again. I need assistance please

Random lag spikes

Hi,

We would like to know more about your lag issue:

• What browser are you using when you experience a lag?
• Does the lag occur in a particular game?

In the meantime, we suggest you run the System Maintenance troubleshooter. Here are the steps:

• Press Windows Key + X.
• Click on Control Panel.
• Select Troubleshooting.
• On the left pane, click on View All.
• Click on System Maintenance to run the troubleshooter.

Looking forward to your response.

 

One key has severe input lag but every other key is fine

The thing suggested by @lx07was yet another step of trouble shoot you need to perform to role out the hardware fail possibility than rather a topic for debate .
I honestly did not suggest it just because its level of technicality is a bit high and I am not quite sure about your level .
Yet however if you can do that step I can't see why not .
And yet even if you still manage to get lag you are down to the route I just discussed in my previous post , nothing more to do .

P.S I am not even sure what you mean that the button performs well if you change layout , the aussie & u.s layouts do not even acknowledge that button and most probably assigns a different function / key to which hints the conclusion of your test might be slightly biased

 

Video and audio lagging on Windows 10

I have tried every step that you suggested with no good results. I have a TOSHIBA SATELLITE L675D-S7049..

The exact problem is the video and the sound lags and makes a buzzing sound . it does it on all videos and sound. even on iTUNES
