Unplug all USB devices except for keyboard and mouse, assuming they arent PS2. Check for the message again. If no message, well, plug in peripherals one at a time until you see the error message again.
If no change, unplug mouse, retest. If it is a new build, you might have hooked up something a pin off/upside down/backwards on the internal USB headers, check those. Unplug all internal USB headers. Could be a short in the case's wiring harness.
Heck, take a flashlight and check to see if there is anything metallic lodged in a USB port.
Also- Control Panel<Device Manager<Universal Serial Bus Controllers<Generic USB hubs/USB Root Hubs Check for any yellow exclamation marks. doubleclick each "USB "hub" and click the "power" tab. It will tell you the draw of whatever components are hooked to a port. If you have an overdraw warning, and nothing is plugged into the port, there is a short somewhere.
