My mouse scroll wheel stopped working.  Can it be fixed?

If it's just the scroll wheel on an optical mouse, you can try Start-->Control Panel-->Mouse and check the setting for the wheel. But because the wheel portion is a physical device (unlike the optical portion), it can fail.\n\nYou can try rapping and tapping the mouse on semi-hard surfaces to see if some vibration will help the wheel set back properly if so. Tap it on a hard desk covered by a few sheets of paper, for example.\n\nMake sure you try using the wheel in several different applications to ensure it's not just a problem with one application. If it's just a problem with one application (such as your web brower) there could be a setting found from a menu such as Tools-->Options that will allow you to set how you would like the wheel to operate.\n\nFinding a way to open it and clean and check inside would be best. You can also try compressed air through any gaps or edges in the housing of the mouse to try to blow loose the gunky dust that can accumulate in computer mice.

the probabilities\n1) your mouse needs repair\n2) the cable problem\n3) the sensors are dirty (Just open the mouse from the bottom see if the sensor's have accumulated dust you can clean it with smoother things)\n4) there are viruses which simply makes the mouse non functioning\n5) check the port\n6) is nothing works just throw the it away and buy a new one its cheaper.\ngood luck

If you are using a ball mouse, you may try cleaning the ball upside down.\n\nIf you are using an optical mouse, try changing the mouse settings in the control panel.

Go underneath the mouce and take out the little ball and dust around it and the inside of the mouse where the ball goes, put it back n then see how it works. if it still does that...get a new one

1. there may be a driver conflict. delete any other driver than the one that came with it in device manager.\n\n2. the driver is no good. delete it and let windows use the generic driver.\n\n3. the mouse is bad. return it to the store. that happened to me with a tablet mouse. i had to return it twice.

I don't really know but you might have "Scroll Lock" on and then you can't scroll down with your mouse or keyboard

Go open it up outside. How would you feel stuck in a bag of dust and lint?\n\nThen I would call an exterminator if you want your mouse problem solved.

Is it by any chance a laptop? If it is, then it is perfectly normal. Many laptops have problems with the onboard mouse due to the tight space around it on the inside of the case. \n\nTry unpluggin the mouse and plugging it back in. You may have to purchase another one.

Sound like there is a loose wire in the mouse or your connection is loose buy another mouse they are cheap enough.This is the cord which you move the most and has tiny wires so this is most likely the cause.

When your mouse veers off to the side and jitters there, that seems to me that your external mouse is conflicting with the mouse installed into your laptop there.\n\nIf you can, try disabling the mouse on your laptop and stictly use the external mouse.  Another options is to make sure that you're not touching the other mouse when you're using the external mouse (or verify that the internal mouse isn't stuck to the side or something).\n\nLastly, being this has happened to you with two different external mouse, try installing the manufacturer's drivers for the external mouse.  Yet since this has happened twice, this may not help at all.

Not surpised the helpdesk could not help. I doubt if anyone will be able to pinpoint the exact problem - with IT often even the experts just uninstall and reinstall in the hope it solves the problem. I imagine there is a conflict with a shared dll. I would try reinstalling your mouse as a device (so it links to all software at same time). Ensure you temporarily stop background operations running (such as Antivirus software) before you do this. Good luck.

Go to the control panel and click on the mouse icon then click on the hardware tab and then click on the troubleshoot button.  That wizard will walk you through your problem.
