macl64 :
thanks to your advice I have made some progress, I went to the Bios Menu and for some strange reason the mouse started working perfectly, so I exited BIOS, went to the desktop and now it is not working again.
Ok, so now we've at least confirmed that your USB port is functional. Perhaps the drivers are just not installed or are turned off? The BIOS/UEFI uses its own individual drivers than Windows does, iirc. I'm assuming you're on Windows 7.
Start > Devices and Printers > Mouse Icon (The name might vary, but it should be the icon of a mouse) > Hardware Tab
You'll now see a list of "Device Functions". One-by-one highlight each listed function and use to the tab-key to get to that function's properties. In properties, ensure that the device is enabled. You'll know it's enabled because it'll give you the option to disable it, and vice versa if it's disabled it'll give you the option to enable it obviously.
If that doesn't work and all the device functions are confirmed to be enabled, then it's a matter of drivers. Try using the same method to get into the properties section of "HID-compliant mouse" and use the update driver button. You'll probably be given the option to search online (automatically) or locally for your drivers, and chances are you'll want it to be automatic. Do so. If that
still doesn't work, then do the same method of updating just mentioned in this paragraph but for "USB composite device" (I'm assuming it's a USB wired mouse, but if not, then whatever input device you're using).
