It looks like you have a motherboard with an ATI chipset.
Try downloading the latest drivers from your motherboards manufacturers website ...
Hint when you first turn your computer on, the manufacturer & model will flash up on screen ... prepare to hit the "Pause Button".
Download the drivers for the motherboard chipset.
Since you are using USB mouse, it gets slightly more complex.
Install the drivers, and then right click on "My Computer" ->Properties
If you're running winxp, you can click on the "Device manager" tab, vista or W7b, you click on the Device manager link in the left pane.
Select View->Devices by connection.
Most likely in the PCI bus, you need to find the USB devices. Click the plusses to expand them. Find your mouse .. and don't delete it
Delete all the USB HOST CONTROLLER's (except the one that's connecting to your mouse) and then reboot your computer.
On next startup, windows will detect the USB devices & reinstall the updated drivers.
You can also try just deleting all the USB devices (except the one that your mouse is connected to) and rebooting. It'll probably also do the same job, without getting the latest drivers.
