I have a dfi lanparty nf3 motherboard and i just got the nf4 motherboard. I took the nf3 out of my case and setup my nf4 board. And now I?m trying to get my nf3 board to work and the only thing i have different is the video card and i check to see if that card works and it does. But I cannot get it to boot up I get a long beep ever other second. I?m not sure what the probable is because is I put different ram I cleared the bio I tired two video cards they are both order card 64mb cards I had a 6600gt in it and never had a probable. So if anyone has any idea I would really appreciate it.
