I have a Pavilion s3120n Slimline PC. I purchased the HP recovery DVDs and reloaded my PC. I am running the Vista (32-Bit) operating system. The motherboard is an Asus M2NC51-AR and has an Nvidia GeForce 6150 LE/nForce 430 Chipset.
For some reason the USB devices come up as unrecognized. All of the cables are properly connected to the motherboard. None of the pins are bent or missing. The connectors on the motherboard control a 15 in 1 memory card and 5 USB 2.0 ports, 1 on the front and 4 in the rear.
Can anyone suggest a solution for this problem? Is the motherboard defective? Does a PCI card exist that would support the cables that are currently attached to the motherboard?

Disconnect any external devices except the Keyboard ,mouse and monitor. Go into the device manager. Right Click the Computer select properties, then Device manager in the menu upper right hand side choices and look for USB items,Ports/Hubs. If they aren't there you are missing a driver If they are there. Uninstall the drivers and shut down totally reboot and then let windows detect the hardware and install the drivers. The drivers are here. http://h10025.www1.hp.com/ewfrf/wc/softwareCategor
