I just put together the parts for my new rig. I placed the motherboard on a static bag on its box. Installed CPU, heatsink and fan, memory and video card. Connected the PSU.

Now when I try to power on the system (by shorting the Power Switch jumper) nothing happens. I see the power supply connected and on LED "on" and the digital display on my Abit AN8 SLI motherboard reads "01". After shorting the power jumper it reads "83" whic according to the mannual means the PSU is ready.

No fans turn on. Nothing else happens?

Do I have a dead mother board or what??? :mad:
 
My setup

Opteron 148 with Sycthe Ninja 1000 (120MM fan mouted)
Abit AN8 SLI
Gskill 2GB PC4000 memory
7800GT Evga
Antec HE500

Those are all the parts I have plugged in for now! And there are no beep codes or anything.
 
I unplugged a ATX4p1 connector from the mother board. Now the CPU fan and mother board lights come on. The graphics card fan is also working. the uguru read out goes throw several display no.'s but finally reads "7F" and then doesn't change. Still no display on moniter or beep codes?
 
does the PC4000 memory have anyting to do with it. I know by default AMD boards only suppoert PC3200. Also I had a fight a little to get the heatsink (ninja) on my CPU. I think I used more force than I would think neccessary. Is there a chance I might have damaged the CPU? Also I put a dab of artic silver on the CPU but couldn't fit it on the first time. I had to take the heatsink off and put it back on again. I hadn't powered it on so I didn't clean the stuff on their cause it was wet and only been less than a minute?
 
Are you sure the power supply is properly connected to your motherboard?

Do you have an SLI power connector on your video card, and if so do you have a lead from your power supply connected? (with adapter as neccesary)

Try clearing the CMOS with the CMOS jumper?

Also are you connecting the CPU heatsink fan to the proper pin header on the motherboard? Some motherboard's default behavior will be to refuse to boot unless they detect an RPM signal on the pinheader meant for the CPU fan. You can usually get around this by holding down the INS (insert) key in your keyboard while pressing the power button (or shorting the pins meant for the power button on the mobo).
 
Try using 1 RAM stick.

Use the 4 pin molex power at the bottom of the board.

Chances are you didn't damage the CPU, but you might have broken some motherboard traces if you had to bend the board a lot to get the HSF on (probably not though...they are pretty resiliant).
 
yes the graphics card is connected to the PCI-E power connector. Also I did try to reset the CMOS a no. of times.

Does anyone with a similar board know more about he codes on the read out of the motherboard?

You put it on the outside of the anti-static bag? Thats your mistake. Only the inside is static proof. So if you're going to use it as a surface you need to cut it open and put the inside to the top.

Anti-static bags take the static from the inside and "suck" it to the outside. So if you put anything on the wrong side (outside), especially ram, it kills it.

Jesus, you didn't know that!?

ok, j/k but I thought that would be funny.
 
Make sure the fan is hooked up to the right header my AA8 wont boot unless it is hooked up I have to rig it to use my HSF with a external controler. It would do what yours is doing spin up then shut down
 
The HSF is connected to the header marked CPUFAN1 on the motherboard. THe computer doesn't shut down. It powers up. Everything seems to be working fine now except that there is no signal to moniter. IF the memory were dead than shouldn't there be an error code regarding that? I will test my memory today with a hardware memory tester to see whats up. I will also try a different stick of PC3200 memory to see if that is the only problem here. Like I stated earlier the Ugugru display goes throw a no. of post tests and stops when it reaches "7F" if I press f1 on keyboard it says "FF". The manual says this about codes

7F - Switch back to text mode if full screen logo is supported
-If error occurs, report errors and wait for keys
-If no errors occur or F1 is pressed to continue: Clear EPA or customized logo


FF-Boot atempt (INT 19h)


I understand there is always a chance that I might have fried something. But I was very careful with all parts. And yes they were on the anti static side of the bags.

I just got off the phone with ABIT tech support and they tell me that code "7F" has got something to do with my video card. They told me to put the card in normal mode (non SLI) and have the power cable connected! (Duhh!) So no help there!!!

Please I am desprate here. I have spent too much money for this to not work! Totally furstrated and sleepless at the point. :(
 
do you have a spare cheap pci vid card? try that.
or try the vid card in another machine... could have a bad vid card, it happens man. i got 2 in a row once :(
 
The most likely suspect is the video card.

Am somewhat surprised that the Abit reps didn't suggest what Double Jesus did.

In any case, Abit has a pretty good RMA service, so in the event your board is hosed, you should be okay to send it back.

PCI vid cards don't always work as a primary display adapter in newer PCIe motherboards. I had a few boards that wouldn't post at all with just a PCI vid card. It needed a PCIe one connected to post :(.

even after cmos reset with the pci card in there?

my msi board won't post unless the pci vid card is in the bottom pci slot... (after cmos clear)
 
Yes even with a CMOS reset. It was a Chaintech VNF4/Ultra board that I first saw the problem on. I was waiting for my X800XL to arrive and I wanted to use an old RageXL :). No go though :(. I don't know if it had to do with the bios option for first detected vid card, but it never did post. All it did was blink the Power LED at me.
 
I tested my video card and memory in an other machine and they are both fine. Any clues??? on what else might be the problem here. Please I am desprate. If I have to RMA the mother board, if I shorted it despite be catiious. Is it gonna fly with Abit or are they gonna give me a hard time about it? The last thing I want to do is get a new MB and run into the same problem ... code 7F!!! and no signal!
 
-Take everything out of the case.
-Unplug/remove all components.
-Clear the CMOS.
-Assemble the CPU/HSF, RAM, vid card, and mobo on a piece of cardboard.
-Attach power cables.
-Use a screwdriver to short the PWR pins and fire up the motherboard.

If that doesn't work, based on the results of your RAM and vid in the other machine, get a replacement for the motherboard. Abit doesn't care what you did to the board, they'll just throw it on the 'bad' pile and pull one off the 'good' pile for you.
 
The one time i had a problemb not booting up it was the processor it had a couple of bent pins well good luck I know the aggrevation
 
tommorrow morning I will try out a PCI card and see if that has anything to do with it.

I work at Bestbuy so I have access to everything I need. I will try all my parts on a different machine individually to see if I can narrow it down to a bad motherboard (of which I am getting more and more certain)

I already kow that my PSU,memory and Video card are ok.

I will test the processor in a different motherboard to make sure that is working fine as well. All I would need than is to get an RMA for a new motherboard.

Anyone who has delt with Abit customer service before? how long did it take for yourrreplacement parts to arrive from the day you shipped out your bad Mobo. Also do they send new parts or do they just fix the same parts and send them back?
 
I got another response from Abit through email. They claim that Abit AN8 motherboards do not support Opteron CPU.

Is this correct! How could I have missed something so vital???
 
They say a lot of things they don't mean ;), especially since s939 Opteron CPU's are identical to regular San Diego s939 cpu's just with different identification strings.

Shit happens, even to 1337h4x0rz. Ask any one of us if we've trashed hardware - processors, video cards, etc. and you'll get some amazing answers. I remember burning up three CPUs on one platform, simply because I was attempting to prevent condensation from a Pelt. Not that I'm mister hardware, but you get the idea.

By the way, it seems there are some differences in processor architecture between the Opteron 939 and the A64. The main one has to do with the number of HyperTransport links (3 for Operon vs. 1 for A64).

You might have to wait for a BIOS update in order to run the thing, or, as Abit tech support says, they may not have made any provisions for running the S939 Opterons on your platform.

Abit tends to have tunnel vision. I still get urked thinking about the KT7A situation, whereby we were left without an upgrade path to Palomino or Tbred. By comparison, Asus comes out with BIOS updates ever other day.
