Anytime you have problems like this, you need to make sure to check the basics first. Are the wall outlet and power cord both good? Plug another electrical device into the outlet to make sure it is working, and try connecting the computer with another cord.
Now that we know that there is power to the computer, look for any lights on the computer when you press the start button. Also look for any fan motion. A common problem with a faulty motherboard is that as soon as you press the start button, the power supply fan with try to spin, but will immediately lose power. Do you smell an "burning" type odors coming from the power supply? If so, you probably have a bad power supply.
At this point, you have to decide if you want to repair or replace you system. If you are truly running a pc with XP or Vista, you may want to consider upgrading to a new system. Your hard drives in your old system are probably okay, and if you purchase a new system, the drive may not be compatible with the new hardware. Older systems typically used IDE interface for hard drives whereas current systems mostly use SATA. The connectors, both power and data, are not compatible. You can purchase an external adapter which will allow you to connect your older hard drive to the newer system via USB, but you will have to re-install all of your older programs on the new machine, and hopefully, they will run on the new operating system. There should be no problems migrating your data files, music, photos, documents, etc. to the new machine.

Does the 'USB' branch of the tree show the USB ports?
Is there an 'Unknown Devices' branch of the tree?

Either way, the software "device-drivers" for the USB ports are not installed, or not installed correctly, and so you'll get the symptoms that you've observed -- power without device-recognition.

Access and click "Detect My Computer", and download and install the device-drivers for the USB ports.
