DFI Forums - NO BOOT 3 LEDs LIT. OK, here is a strange problem that has just cropped up.
The DFI LanParty nf4 Ultra D seems stable, but when you turn it off and then back on immediately, the system hangs with 3 LED lights on and the speaker beeping. This means that no ram is detected. If you wait 20 minutes, it boots fine. Very strange. I bet it is related to either the new Athlon or perhaps to the use of OCX VX ram at 3.4 volts. Maybe, the voltage doesn't get applied right?
There are related posts on "warm boot problems":http://www.dfi-street.com/forum/showthread.php?t=10822 where folks are focused on the video card, but in general, there seems to be some sort of BIOS problem.
Another fellow thinks it is the "OCZ VX":http://www.dfi-street.com/forum/showthread.php?t=10572 and essentially, you have reflash with some special parameters.
Apparently, there are beep codes that occur. The beeps I hear are just a single beep, beep, beep. It is like Morse code for computers 🙂
