My friend has just recently put together a new comp. Its a LANPARTY NFII ULTRA B mobo with an AMD Athlon XP 3200+ chip. Everything is in for sure, and everything is hooked up correctly. Just for reference, he's running 512 of Corsair Value Select RAM in DIMM slot 1. We didn't get any post beeps on power up, just a blank screen and all 4 of the diagnostic LEDs were lit with all fans and power running. Any suggestions?
