Buy a new one and see if that cures the problem.

for some mouses, there is an installation cd and you should install before you connect your mouse in usb slot.

If there is no installation CD then the wire connecting mouse to usb must have been ruptured

You haven't said what kind of mouse you have or whether it used to work.
I'll offer some suggestions for the most common problems:
If it used to work but now doesn't, try a system restore back to when it did work.
If that doesn't work--are you using a wireless mouse? If so, are the batteries fresh and are they inserted correctly?
If you are using a wireless mouse, have you pushed the little "connect" button on the bottom?
You haven't said, but is the other mouse a wireless one or a USB mouse? If your USB mouse doesn't work, try another USB port. If you go into the device manager, do you see a "human interface device" or a "mouse" listed? If so, it will tell you the system recognizes the device. If that is missing, there is a good chance the mouse is dead.

Have you checked your battery on the mouse? I would pressume that it uses battery since its wireless. Does it have a on/off switch? Because for it to work you need to turn it on. Can you post the exact model and specs of your wireless mouse? For us to better understand what were dealing with. Reply back. Good Day.

try a different set of new batteries.

Check whether your mouse connection is working fine.if it works restart the pc and it would work.If Doesn't you need to switch to new mouse

Check with fresh batteries.. Did you sync the mouse with transciever? Push tiny button on transceiver, (maybe hold for few seconds) light flashes quickly.. then push tiny button under the mouse, light stops flashing. Try few times, maybe otherway round. If still not work consider defective.

mouse cliock buttons have become faulty get it replaced from hardware repairing professionals

sounds like you need to resync the mouse to the wireless receiver that is connected to the computer.

The manufacturer no longer has the drivers on its web site nor could I find drivers on any of the archive sites I?m aware of. If you?re in love with this mouse I would try emailing Sakar (http://www.sakar.com/about.aspx) to see if they will send you the drivers for your operating system. If that doesn?t work you could try just letting Windows try to find/install the best driver it has. If that doesn?t work it just might be time for an upgrade.
