Windows 7: Mouse is sometimes jumpy when CPU is loaded

31 Dec 2012   #1

Windows 7 Ultimate 64-bit SP1
Mouse is sometimes jumpy when CPU is loaded


This happens on my netbook NOT on my listed computer

Netbook specs:Samsung N145P w/Atom N455 and 1GB RAM & Windows 7 ultimate.

Lately the computer mouse becomes very choppy and laggy (not smooth) when doing tasks like loading pages or anything that uses CPU, this happens on both touchpad & external mouse. Updated drivers without success does anyone know why

Many thanks.

Hi Derek10,

The cause of this is most likely because you only have 1GB of RAM installed in your netbook. It's a very common thing with such low RAM.

You can try checking your RAM usage under "Performance" in task manager.

Hi Andrew

This issue seemed to occur recently but I can't recall what I did. Sometimes the cursor gets stuck for some seconds like it was frozen but music continues to play fine and HD light blinks. My memory usage is at half (500) and 800 when browsing.
