Mouse jumping to bottom left corder randomly

I have another computer where the mouse recently started jumping to the bottom left corner at random times. When it happens it will continue for a few minutes jumping down to the corner every 1-5 seconds. It may happen once a day or 20 times a day. It started recently, soon after I tried to install a driver from for a scale. The scale is Serial port.. old mice are serial... there is sort of a connection there?? BUT I tried several different mice in the PS2 mouse port and a USB mouse. I also uninstalled the scale driver, did a system recovery... installed a new mouse driver from Logitech... nothing helped.

I had a similar problem! Only my computer was having connection problems with another peripheral device that was plugged in. Every time the device would reset, the mouse would jump to the corner.

The device in question was a rather old Wacom tablet, but it could be possible that your problem is as overlook-able as that. Do you have a second input device?

What I'd try is go into the BIOS setup, and set your serial port for COM1 IRQ4 (Interupt) and 3F8H (address), if these latter notations are listed. Often, you will see the serial port, parallel port, etc. set to Auto. You may want to see if the PS2 port can be set to a specific Interupt and address also, just as long as the settings are not in use by another device. These kind of problems can be hard to pinpoint, but hopefully the above will solve your issue.

USB mouse is jittery

Try the mouse on a different surface, also be sure you do not have any light directed at the mouse - this confuses the eye. Although no mouse pad is required for an optical mouse, sometimes it helps

Jumping cursor

This is a really common problem thats not actually a problem.
Go to trackpad settings and make sure tap to click is off.
Most laptops allow you to tap the track pad to act as a mouse button, try it go to an icon tap the trackpad youll see that the icon highlights as if you are actually left clicking.
When your typing the trackpad senses your arm or wrist occasionaly and thinks your tapping the mouse, thus moving the cursor.
So go into trackpad settings and turn off tap to click.

Mouse will randomly double click or have to click several times to work

Please check whether there are any buttons on the side of the mouse you may be clicking these at the same time as you are single clicking.

You could also try going into Control Panel --> Mouse
Try Slowing down the double click speed
If that doesn't work try speeding it up

Another problem with a laser mouse is it jumps around the screen randomly if there is a pattern on your mouse mat or desk, or if either are too shiny or even glass as the laser reflects incorrectly on these type of surfaces.

In windows xp go into start menu, then into control panel then click on appearance and themes, then move your mouse over to mouse pointers click on it , uncheck "enhance pointer precision, and click apply, that will stop the mouse from acting crazy, this will work with dell mouse pointers and most.

Mouse cursor moving by itself

i have latitude c610 and same problem happens with me too. i think that happens when i finish my brakfat and without cleaning my hands start using the touch pad. what happens according to me is that small particles of food(eg bread/dust particles) stuck in the corners or the body wall where the touch pad ends and keeps pressing the touchpad, thus causing the mouse to move to one direction. when i clean the corners and sides of the touchpad, it starts working ok !!
