Since publishing our review of the X-Fi sound card, i've heard about incompatibilities with the X-Fi and certain nForce 4 motherboards. The symptom is quite simple: blank screen when your system's power is turned on (no sync). If you're one of the few customers suffering from this problem you can either wait for a BIOS update from your motherboard manufacturer or ship your X-Fi back to Creative Labs to have the EEPROM replaced (which is something the user can not do themselves).
