Question about Dell Optical USB Mouse opmse-5

Dell Optical USB Mouse

I have a Dell Optical USB Mouse (DP/N: OT0943) and when using sometimes the Mouse cursor will randomly jump to another location on the screen. If I am playing WOW it will cause the character to spin. What is causing this?

    This mouse is just a plain two-button mouse with scrollwheel and I could not find any drivers for it on the Dell website. Since it is such an inexpensive mouse, would it be quickler and easier to just buy a new one instead of trying to make this one work? I just want to make sure that if I do go to the expense of buying a new mouse that I do not start having the same problem with it. It would help if I were to know the root cause of the issue. The mouse is original on the PC and did not do this for a long time. Can these mouse devices have issues like this over a long period of time? I don't know hardly anything about them internally. Also, I notice on the bottom there are some hairs (mine) in the hole pointing down from the laser. Could these hairs cause this behavior?

    When connected to the USB port, the mouse listed below may experience a jump in the mouse cursor or some erratic behavior from time to time. If your mouse is connected to the PS/2 port, you will not experience this problem.

    To resolve the issue, try downloading the latest version of the mouse software from Dell website. ALternately, you can try getting a USB to PS/2 adapter and use the mouse on the PS/2 port. (The round port behind the tower where you plug in the mouse)

    Yes, the hairs can have an effect on the pointer movement, but not randomly jumping to another part of the screen. There have been known issues when using MS Intellipoint software (which Dell uses for the mouse) with Windows XP SP2.

    I think the easiest fox would simply be to go out and get a new one. I always recommend the corded variety as they tend to have the least problems and have a longer life than the cordless variety which are prone to various problems.

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

Mouse stops responding randomly

The issue may not necessarily be with the mouse. Are you able to use the keyboard once the mouse freezes? If you not even able to use the keyboard, there is some application installed on your computer or a virus due to which the mouse freezes. If, in case, the keyboard works even though the mouse is stuck, try changing the USB port or try a different mouse. Please revert back with any other observations. Good Luck
