My headset (steelseries siberia 800) stopped working yesterday out of nowhere. The errors i get are, "Unknown USB device (device descriptor request failed)" When i plug it in to any USB port it say's " the last usb you plugged in malfunctioned". Other problem is now when i bootup my computer it takes over a minute to get to the login screen (used to be 15s) and my keyboard and mouse don't connect (light up) until 45-50s when it used to be under 5. Any idea's whats wrong? PSU? MOBO?
