I just put together a system and it wont post. All the fans spin up, and the light on the vid card comes on, but nothing to the monitor. No beeps either (using the buzzer on the mobo that is). All four of the diagnostic LEDs on the board are red.

Secs:
DFI LANParty NF4 SLI-DR
A64 3700+ with stock cooler
2x 1Gig G.Skill Extreme DDR500
BFG 7800 GT OC
NEC DVD burner, WD160 gig PATA HDD
Antec 500W SmartPower 2

I tried with one stick of memory, still no go. Also, will a system post with no ram?
 
no, it won't post, but it will give you a bad memory beep code.. Did you plug in all power connectors..? maybe try different vid card if you have one..
 
No, it won't post without ram. As mentioned above, do you have all four power connecters attached to the mobo? Which memory slots were you using? Did you try all four with just a single stick?
 
Unfortunately I dont have another pci x or pci card to try. Yes, all 4 power connectors are plugged in. No, i didnt try a single stick in every slot, but will do that when i get home. I also have some known good ram I can try. If the proc were dead, would those lights on the mobo come on? Do those light indicate that the mobo is good?

edit: Since my case didnt come with a speaker, I set the jumper on the board to use the built in buzzer, but I still get no post sounds.
 
I've tested the ram and its good. I going to go ahead and say the proc is bad, cause i'm assuming the diangnostic leds on the board is not detecting a proc.
 
i had this same problem with my a8n-sli deluxe...motherboard is at fault in my instance.
 
I would look at the CPU, not the RAM, follow what your graphic on the lights shows you.

It goes to 3 when it detects CPU, 2 when it detects RAM, then Video and then the last light goes away after the list of the IRQs / I/O Address List.

Clear CMOS, check the safe boot jumper, make sure its on pins 1-2, make sure the molex plug on the board is connected.
 
Yea, I did the CMOS reset and even took it out of the case to make sure nothing was grounding and all 4 power connectors were connected. I'm guessing CPU, cause if it were someting else, at lease the first diagnostic LED would have went off (meaning CPU detected). I thought it was suspicious that the green packing inside the CPU box was like ripped in half when i got it. but nothing appeared to have been tossed around, and i'm think it'd be retty hard to physically damage a CPU sealed in the little plastic thing.
