Possible dead Mobo - ASUS a8nsli-32 dlx

I just got home from work and my pc will not start.

The build is the following; Asus A8nsli32- deluxe with 2x6800 s Gt, 2 Gb Cosair 2500LL, hyper psu (R type).

The first thing I noticed was just the hdd led on and no post beep. I switched off did an ATX reset and then got both power and hdd, solid. No post. The fans will turn, GPU fan turns and the light on the mobo comes on by the PCI express slot, and I get a single light on by the memory (Its the TWIN X stuff with the LEDS- Normally a row of LEDS will flash)

Got alittle worried at this stage and I took out 1 of the VGA cards, 1GB of the ram and swapped the sockets as well as reset the CMOS. After resetting the cmos the pc started, but no power to keyboard and I could not get into the bois. just hung on no system disk (I had disconnected all drives).

After resetting again there was NO post yet again, I have found that I have to reset the cmos in order to get it to post once. Then when I either restart or reset there is no post until another cmos reset. This is wieired.

I have ruled out that it is not the PSU - I have tested another PSU, Not the memory (Impossible to be 2 faulty sticks - well 99.99%), and not a faullty video card. It either leaves the CPU or mobo to be the cuase of the problem.

I tried reseating the board as the next step with no luck. Is there anything else anyone can suggest I do, or is the board busted. Its wieired that it works once and then not again. It sounds like a seating problem but whatever I try does not help!!!!

Secondly if it is my board is faulty. How do I go about RMA with ASUS ? Could someone help me ?

Many Thanks

I have the earlier version of this board have found that if the dvd is dodgy it will fail to post with a hang.

Can only suggest you try a rebuild with minimum hardware along with a good clean, before you RMA.

Sometimes a little attention is all it needs else wise it does sound bad though.

I tried this but inside the case, everyone stipped down including the cdrom. The most odd thing I found was the machine would start after sucessful reset of the bios. after I press the reset switch or power off and back on. I would be back in the same boat.

I phoned overclockers this morning. Unfortanatly I do not have my anti static jiffy back for the board, can i send it back in bubble wrap, if so I can pick some up easy? This is the first board I have had fail on me!

Can get bubble wrap from the post office - they sell it quite cheap in massive rolls

Just done a quick Google with power model make and motherboard make and boot up problems.

Seems there are issues with this board need ing a bios update.

Some seem to be having identicle problems to yours

Do not kow if there is a solution or not but you may find something useful.

I would be most greatful if you could forward the result of the google searches to me, I took a look myself, seaching asus.com.tw, by the way the machine had the lastest bios when it had the problems.

sounds familiar, my problem was caused by the fact that i had upgraded the bios. USB keyboard wouldnt work, so use a ps2 dongle. *** u need to do, is press and hold f11, when u turn it on. (or pull out lead for couple of mins) defaults to standard settings. Get into bios if possible, goto advanced-Memory settings-memoryconfigurations-

now in there turn the memlock limit on, and limit the mem clock value too 200Mhz. What I found was happening was the memory was being set at ddr500, not 400. My system didn't like that at all. Bearing in mind I can get a stupidly high fsb on my chip mobo and mem. But for some reason it wouldn't start with the mem lock on 250mhz!!!?? crazy. Mine was doing exactly what you are describing, wouldnt post, then it would and keyboard wouldnt work etc.... 2 days I messed with it. But in the end thats what i found my problem to be?? Try...

This was doing my head in so I decided to try this morning an out of the box build just on the desk, I needed to be sure it wasnt a motherboard leg or bad aligmnment of the board.

This is the first time I ve done this, so I need to be sure what i did was right, I layout it out on cardboard, on the mobo box, installed the following

- Atx power connector, Ez connector and 4 pin connector
- regreased and reseated the cpu connected to cpu fan header.
- Installed 1 6800 into the Blue slot (which i am 99% sure is the primary
- Installed 1 stick of the 3500LL Twin x cosiar ram

shorted the power pins to force it to come on, CPU fan spin slowly. If I remove the 4 pin connector it spins fast. Something is working. Still no post I had the speaker connector also plugged in from the case still no beeps.

All I noticed that when I press the switch is the Amber light on the RAM comes on for about 5 seconds and then goes off.

- So I tried another VGA card and another stick of ram, and I have tried my other graphics card. (This is normally SLI), still the same results.

I cmos reset or removing the battery does not help, If I am getting no no beep I also get no display and no bios to go into.

After disaseembling the system very shortly afterwards I did notice that the CPU socket heatpipes and cpu heatspreader was stone cold! To start off I thought it would be the board, but there may be a faint chance its the CPU as well.

I dont think there is anything I can do now, I contacted O/c and they have advised me to send in the CPU also. (amd 64 3500+)

I am in summary very disappointed with this board. It has always been twitchy regarding memory settings and I fully agree with what you said in the last post but there is no way of riasing it from the dead this time.

Has anyone had any expierence on sending back the board I have no idea on how long its going to take and what they are likely to do?

Thats the link you need to read through a lot of bumf as well.

Dont know about RMA last time I had to RMA it was to the reseller and they just sent it back again incompatable parts or something meant they had no liability.

sounds Borked TBH!!!

I tried it with a jeanteck 400 watt psu with just the core installed, so it cannot be the hiper issue. Ill read up on the link anyhow Thanks.
