Help! P5NE Sli Not Posting

Hi all,

I wasn't sure if this was the right place to ask for help, so forgive me if I've misplaced the thread. I have a computer that I built about 6 months ago now. It has an Asus P5ne Sli m/b, 6400 Core 2 Duo proc, evga 8800gts 640mb, 2 gb RAM. The computer has worked flawlessly up until now. This morning I turned the computer off as usual through the windows start menu, and now tonight the computer will not post. I have not installed or changed anything on the system recently. I tried clearing the CMOS by removing the battery and changing the jumper, but this did not help. The monitor appears to not be getting a signal as it remains in standby. I tried reseating the graphics card as well as checking all connections to the PSU. Everything seems to be getting power as the graphics card's fans are spinning, as are all case fans. The computer does not beep or anything when trying to post, so no BIOS error code that I can distinguish. All I get is the blank screen and the sound of running fans. Any ideas/help would be appreciated. Thanks!
 
Thanks for the prompt reply.

On your advice, I tried removing each stick and then trying them, one at a time, in each slot. Sadly, there was no change.
 
Tried reseting the CMOS beforehand, but since I am here asking for help, I tried it a second time just now. No luck. Thanks for your help though.
 
In sure and certain hope of the resurrection to eternal life through our Lord Jesus Christ, we commend to Almighty God our brother P5N-E SLI; and we commit his body to the ground; earth to earth; ashes to ashes, dust to dust. The Lord bless him and keep him, the Lord make his face to shine upon him and be gracious unto him and give him peace. Amen
 
I take that to mean the board is likely dead. I suspected it might be so, but didn't want to believe it. Any ideas on how this might have happened? Also, is there any chance that this could be the result of a different component failing? I'd hate to go through the trouble of a complete system overhaul to switch out a motherboard that in the end wasn't the culprit. Is there any way for me to confirm?
 
if the boards dead it should still be under asus w'tee 12 months u get. not a major overhaul just a board swap i had one die on me and had to get it replaced no problems since. and for your sake i hope its just the board and it hasnt taken more stuff down with it.

sounds like a cap mighta went, only way to test if its not the board is put the components into another board
 
Agreed. Youre not getting image, its before post. It can only be a few things. Motherboard, RAM, CPU, GPU, PSU. I doubt its PSU, since likely nothing would happen, ie no spinning fans. Youve likely eliminated the RAM as a culprit, since its highly unlikely both failed at the same time. Youre down to CPU, GPU, Mobo. If you have an old GPU to try, thats another eliminated. CPUs are pretty tough these days, so i doubt its your CPU, but still possibly. My bet is the mobo was just at the end of its life, but you need to do your own testing to rule it out. Most of your hardware should still be under warranty though, so no worries.
 
Well thanks a lot for your help, all. I really appreciate it. Guess I'll be looking into the m/b warranty. Thanks again!
 
Have you tried booting with just power supply, motherboard and CPU and see if you get memory beeps, or post beeps with NO hardware in it?

If you do add memory back in 1 at a time and see what happens.
 
Hi,
I'm having the almost same exact problem. Im running the same m/b and the same gfx card (MSI nvidia 8800 GTS 640mb). I'm also running 4gb ram (kingston ddr2 667mhz) and a core2duo 2.33ghz. I've tested the ram and there is no problem
This is a new build, only about a week old. The problems started happening right from the beginning. It boots up, but on a restart, it will not post. No bios error message/beeps or anything like that. The only way i can get it to start again is by turning it off, giving it about 20 seconds break and turning it back on. This works about 30% of the time .... I just repeat it to get it working again.
Once the system is running, it seems very stable (i played about 6 hrs straight of bioshock with no cpu overheating, crashes/freezes etc).

i've flashed the bios to the latest version but this did not get rid of the problem.

When it does not post, the cpu and all the fans seem to be running. Could it be that the psu is not supplying enough power? Its a thermaltake 430w silent power supply. I checked the voltages and they all seemed 'correct', but i'm no expert when it comes to psu's and voltages/amps etc.

Any help would be appreciated =)

Change your NB Voltage to 1.56v and set your timings manually in the bios. See if that helps you. I skipped the 0706 bios and kept the 0608 bios due to better OC results. I was getting tons of bluescreens, and no post. Remove 2 stick of ram to get it to post and set those settings manually and see if that helps.
 
you could have a short someware happend to me once with that board, I just took everything appart and put it back to the gethers and it worked.
 
Gah... things just seem to be going from bad to worse @_@.
I tried what Sean suggested (ended up going late to work), but i couldn't the machine to post at all this morning so i could play with the voltages! If I had built this myself i would have pulled it apart and redone it, but since the techies at the hardware place put it together, I'm just going to take it back to them. I don't want them to accuse me of having stuffed it myself by playing with it.

Grrr, i knew i should have stuck to a gigabyte motherboard >:\
 
This board is known for major problems with more than 2 physical sticks of RAM in the system. I tell you one thing, I played with it for almost 1 week, crash after crash after crash. It pissed me right off. I am now getting nothing.

What PCI cards do you have in the system? I had a no post once, and only once and I resolved it by removing the sound card I had from the bottom PCI slot. It posted fine in the 2nd to bottom, but wasn't being detected. So I swapped spots. No post. So I took it out and cleaned the connectors. Put it back in the 2nd slot and it posted no problem. Funny enough, its now located in the bottom PCI slot due to SLI.

Bring your board down to CPU, Power Supply, Video card and 2 sticks of RAM. Clear the CMOS and try posting. I do wish that ASUS had some post code or something on this board, other than beeeeeeeping. Sheesh.

I'm sorry its not working, my settings worked for me, but I have different components. However those settings worked for others.

Try this link and see what you can come up with.
 
Hmm i have one pci card, a sound blaster audigy card ... I'll give that a try ... gah, i want to get back to playing bioshock!
 
I solved the problem
I replaced the P5N-E SLI with a differnet motherboard, i got a gigabyte GA-P35-DS3L :p

Okay, it doesn't have all the features of the asus one, but atleast this one posts.

At the tech place we tried everything, new sticks of ram, new motherboard, new gfx card, couldnt solve the problem
so at the end i decided to just get a different model motherboard and go home.
 
Well if that's what solved your situation, then great! I do say this board is picky.
