A8N-E no post, no nothing?

[subzero813]

i have an A8N-E board, with an Athlon 64 X2 4200+ processor and thermalright XP-120 heatsink and panaflo 120mm fan... vid card is a geforce 6600GT PCI-e. the case is a 'navigator-x' from Aspire and it came with a 500w power supply (its see through and glows )

i put in the CPU, put arctic silver on it, put on the heatsink, put on the fan. put in the vid card, hooked up the hard drive (a maxtor SATA drive), and plugged in the DVD+RW drive.

i press the power button and everything lights up. all the fans (like 5 of them) start spinning, PS fan is spinning, cpu fan is spinning, vid card and mobo fans are spinning...dvd drive opens up, i make out the sound of the HD powering up...but no beeps, nothing on the monitor. and pressing power again doesn't turn it off.

any ideas? i got the board from newegg, i ordered it monday. what do you recommend i do to trouble shoot it? i have another system here with an antec 430w power supply, but no replacement socket939 processors, or PCI-e video card/motherboards.

it had two connectors for power for the motherboard. a 24-pin connector and a 4 ping connector. i plugged them both in.

i am about to try taking out the mobo and powering it up outside of the case, after taking off and re-installing the CPU. if that fails, what next? is it possible for the CPU to be fried? or would it just be the mobo that i would have to RMA with newegg... and if the mobo is the weak link here, what kind should i get? i don't think getting another one of these shoddy Asus products is too tempting at the moment. (i took all precautions, grounded myself on the case before i touched the thing)

forgot to add
i have two Corsair CMX512-3200PT sticks (in first and 3rd slot, or the two blue slots)

Usually when your computer doesn't turn off you forgot to plug the 4 pin connector into the motherboard.

I'd take off the DVD drive and anything else that is not need to boot the system. Only have the memory, CPU and video card connected. See if you can get the computer to POST.

 

[subzero813]

yep, tried all that. and the 4pin connector is plugged in

1. Is the power led light blinking ?

2. Is there a jumper across the SMI switch pins, I ran into a case were putting a hard drive jumper across the smi switch was required to get the machine to post.

3. Bios is upgraded to the version that recognizes the 4200+ ?


It doesn't turnoff because Asus has a 4 second turn off feature in the bios. Hold the power button down for 4 seconds and it will turnoff.

 

[subzero813]

what are the SMI switch pins and where are they?

 

[13Gigatons]

The SMI switch is a hardware based way to put the machine in standby either S1 or S3. It is located in the same place as the power switch, power led, hard drive led and reset button.

It should have something listed in the manual although they don't bother telling you need to have it shorted. It works by detecting a short to open moment. If left unshorted it can end up booting into standby.

 

[subzero813]

nope, there's nothing like that

 

[13Gigatons]

Ok maybe the bios isn't up to date.

 

[subzero813]

i dont think its possible to update the bios if the stupid thing never even gets past post...i get nothing on the monitor, absolutely nothing. no beeps whatsoever, isn't it supposed to beep at least once or twice on normal bootup?

 

[subzero813]

i found there's two versions of my processor:

i don't know which i have. could this be a problem if i have to set something for the right 'stepping'?

Clear the CMOS and try it with a different PSU and different RAM.

 

[subzero813]

the only other RAM i have are two Atlas Precision PC3200 sticks...i figured Corsair would be better than those, but i'll try them out. and i was under the impression faulty ram at least gives you a few beeps?

i also only have an Antec 430w truepower PS as an alternative, i hear that isn't enough for this CPU/motherboard? i'll have to go buy a 20 to 24 pin adapter first.

Did you figure out the problem?

I have the same setup!!

Truepower II 550 and the Asus Preium SLI...

I had this same problem with my MSI KT8-Neo2, Athlon 64 3400. I rebuilt the whole thing step by step and nothing. I cleared the CMOS and it let me into the BIOS, but when I turned off the PC, I still got no post or anything, not a single beep. Well, it turned out to be a bad bios chip. I sent the motherboard to the manufacturer and they replaced the bios chip in a week.
