mouse and cursor cause the desktop to go berserk!!!!

The computer is 800mhz AMD with 128 mb of RAM using a PS/2 mouse.

The problem is that when the cursor is moved around the display it will involuntarily open up other applications and sometimes it will lead to the display freezing and sometimes the cursor vanishes off the screen altogether.
In these cases you have to switch the computer off and reboot it
The problem occurs when using the mouse/cursor
It does not happen when you are using the keyboard to navigate.
It occurs in both Windows 98 and Windows XP Professional Sso it does not look like it is a software problem.
Has anybody come across this? Any ideas how to remedy it

My first impression is an incorrect mouse driver but since it happens in both 98 and XP, I think that's unlikely.

So the other possibility that comes to mind is that this mouse is just bad and is sending spurious data back to your computer and making it go crazy.

Can you try this mouse on another system or try another mouse on yours?

It might save you some money if you can just borrow one.

Another possibility is your PS/2 port on your motherboard.  While mouse failure is more common (and broken wires in the cable are not unusual) it's also possible for the port to fail.

What do you mean by would not fit?  PS/2 is PS/2.

Again, PS/2 is PS/2.  Either this is a PS/2 mouse or it is not.  If it's PS/2, it will have a PS/2 connector.  If it's something else, the connector will be different.

What BRAND and MODEL of mouse is this?

It sounds very much like a failed mouse.  What happens is the buttons get "stuck" so that it is clicking everywhere you move the mouse and opening programs.  After a while the resources run out and the system locks.
Next time it happens try a CTRL-ALT-DEL at the beginning and use the keyboard to kill off all programs except SYSTRAY and EXPLORER (in 98) and see if it is still happening.  If so, I believe you have just proven it to be the mouse.
