Having trouble with my pc upgrade atm. I basically have a DFI Lan Party NF4 SLI D motherboard but unfortunatly I dont have a manual. When I boot up all the fans come on, inc. the fan built into the motherboard but it beeps. I get one long beep then 2 short ones. Thing is the long beep sounds like it might be to beeps as the beep isnt a clean beep :/ can anyone here help??
