ASUS A8N-SLI Motherboard not powering up

Here is the manual for your motherboard (since describing a diagram probably isn't very useful...)
http://dlcdnet.asus.com/pub/ASUS/mb/socket939/A8N-SLI/e2024_a8n-sli.pdf

You want to look at pages 27-35, they describe what you need to plug into the motherboard. Basically make sure you have connected:

1) 24-pin power cable (from power supply)
2) 4-pin power cable (for CPU from power supply)
3) Any case fans with 3/4 pin connectors.
3) hard drives (SATA or IDE)
4) USB front panel ports
5) Audio front panel ports
6) Case plugs (power LED, hdd LED, power switch, and reset switch).

the boards today have real fine typeset near the connection pins but they are there

It sounds like the front panel wire has either come loose from the motherboard or is plugged into the wrong spot. Recheck the motherboard to see if the wires are in the right place & not loose. Hope this helps.

Are you absolutely certain that your chip is compatible with your motherboard?

imondeau, do you still have you're manual for the ASUS A8N-SLI Premium? Please turn to page 2-12 & 2-13.

The QVL; Qualified Venders List, shows all the tested memory for this board. Edge memory is not supported. This is why the Edge memory only runs by it's self. Once you add the corsair memory they clash because they are not compatible working together in this Asus board. Both sets of memory could work in another board. (Maybe)! What is also needed is if the corsair & edge DIMMs are SS = Single sided or DS = Double sided. How many chips on the corsair? How many chips on the Edge?
They must have the same total chips each each DIMM.

Edge does not sell memory compatible for the
Asus A8N-SLI Premium.

I went through your bios manual three times & did not come across a setting that gives you the option as you listed above.
What I did come across & triple checked your Manual Pg. 2-28 section 14. Asus EZ selector card connector (144-pin SLI_CON.
When using two PCIE SLI cards make sure the card is seated correctly & set for Dual Video Cards. (extreamly important).
Pg. 4-34, section 4.4.9 SLI mode Recommend kepping to Auto. Than the Bios detects the setting of theSLI selector card.
Refering to the sentance above the manual recommends all settings be set to Auto. Your Bios will do the rest. If for unknown reason you no longer have your manual you can download it from Asus. You'll need to fill in the 3 windows under, Please Select the Product.

If your CPU or memory were an issue your Asus board would sound off with BIOS beeps. Asus uses the Award BIOS & you can see what these beeps mean at the link below. Regaurding your PC not able to boot is an issue with your PCIE/PEG video card-in relationship with BIOS setting & the SLI switch card mode that came with your board. When running 1PEG video card you must set this in the BIOS to Auto & you need your SLI switch card connected in its slot. By default, the EZ Selector card is set for a single graphic card. When you install dual PCIE graphic cards on A8N-SLI series motherboards, please make sure EZ Selector card set to the Dual Video Card side and properly inserted.

Will come in handy.
