Windows 10: My Arrow keys Lagging then slowly get better then back to lagging

The rest of my keyboard is working fine, but the arrow keys seem to lag,I don't know what happened or what caused it; it just happened out of nowhere. it slightly annoys me to wait for the delay to go off.

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.

 

Mouse Lag!?!

Basically what it does is remove the mouse acceleration in XP. The mouse will feel slower at first, but eventually you'll get used to it... the only reason why I suggested the mouse fix was because mouse acceleration sometimes causes the sensation of having a laggy mouse (laggy meaning responding slowly). If you meant lag as in jumping around and generally not being responsive, then I guess you'll need to wait for more suggestions *Smile

 

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
