Cursor doesn't work

If the direction keys work and the mouse pointer doesn't, how have you decided that it's not the mouse ?

Presumably the USB port works with other stuff.

But the mouse doesn't, apparently. Have you tested the mouse on another computer or are you talking about a mousepad on a laptop?

If the computer has a PS/2 type mouse connector (or if laptop an external PS/2 Mouse/Keyboard connector) try a PS/2 mouse.


 
the USB mouse works on my laptop, but not in any USB port. But to be sure, I also bought as PS2 port mouse. That doesn't work either.

The curser will move slightly when either mouse is jiggled, but always snaps back to the top of the screen when I stop..

Meanwhile, as I was playing around with the computer, I got a request to "allow access" to an internet website. During this brief window of time, both mice worked. As soon as I clicked on an option, they ceased to work.

This seems to be software related. But I don't know how to correct it, especially since the mouse is necessary to do almost everything.
 
I tested the USB mouse on my laptop. It works there, but not in any of the USB ports on the affected computer. Also a new PS2 mouse fails to work on the desktop.

The curser is fixed in the top middle portion of the screen. It will move slightly when either mouse is jiggled, but always snaps back to the top of the screen when I stop..

Meanwhile, as I was playing around with the computer, I used the mouse keys to active a desktop icon. This led to a request to "allow access" to an internet website. During this brief window of time, both mice worked. As soon as I clicked on an option, they ceased to work.

Thank you, but I tried all USB ports to test the mouse on the affected (desktop) computer , as well as the PS2 port (with a newly purchased mouse) and nothing works.

The USB mouse works on my laptop, but not on my affected desktop. computer
When the desktop software is switching from one application to another, sometimes the mouse will work on the affected computer.

COuld the problem be due to a virus?
THanks
 
The problem seemed to resolve on its own ( after days of not using the computer); But a techie who examined it then said the Start up menu and the Desktop had way too many items and were using 100% of the CPU.
Nothing was left for the mouse. Excess applications were eliminated and so far so good. The mouse works again,.
Thanks everyone for all your help.
