Windows 10: Letters not appearing simultaneously when typed?

Don't know if this is a hardware or computer problem, but think it is computer performance related problem. I have been using a MS Arc keyboard for the last three years with no problems until the last several months. Often times when the computer is first booted up, and for a while thereafter, when typing, the letter output is sluggish. That is, although I'm hitting the right letters, the ensuing words often are missing some of the typed letters. Also, the letters often lag from the time they were typed; I'll types a letter and it will appear a second or so after being typed. This lagging also appears when using the keyboard cursor control; pressing the left arrow, for example, when at the end of a sentence may not move the cursor right away. However, after a while, the letter production does keep up as the letter is typed. Anyway to test the source of the problem?

Touch problems while typing and playing in lumia 535.

When I type then some letters automatically presses like erase button and enter button. Also when playing FIFA automatically it gets touches other points on screen simultaneously at other points even when I touch at other point.

Hi, please post a screenshot of your task manager when this is happening. Organise any column where there is significant activity high to low by clicking on the column tab.

In particular, is your browser doing anything in particular at that time?

And which build of Win 10 are you running? (Windows key + R, winver)

 

Will do when typing starts to drag, but not now. Interestingly, I just booted up the computer this morning to answer your post, but the letters are sync'd with the key strokes, so no problem to report now. However, when things go slow, I'll do the screen shot.

 

I was experiencing a slowdown on boot up and ran my Process Explorer. It appears as though "Ti Worker" may very well be the culprit (How to fix TiWorker.exe high Disk Usage problems on Windows 10, 8.1, 8 - wintips.org - Windows Tips How-tos). At the time of slow down, it was using 25-30% of the CPU. Once it was not on the Process Explorer, things returned to normal.

 

You can
a. check your update history to see if something was installed at that time
b. restrict when updates are downloaded and installed
c. also check if anything is being downloaded at that time

E.g. using (for convenience) Winaero's tweaker (free) - with full technical descriptions of what it does.
I have my updates set to notify me to download and install.

Also check your disk (E.g. Hard disk sentinel (trial) ) to make sure there's no problem resulting in excessive resource usage.

 

Thanks, Dalchina. Always good to know how to handle these issues.
