No beep no display at boot

[NewGuy2]

Intel Core 2 Duo E8400 Wolfdale 3.0GHz 6MB L2 Cache LGA 775 65W Dual-Core Processor - Retail
Asus P5N32-E SLI PLUS LGA775
Gigabyte 512MB 8800GT PCIe
OCZ StealthXStream 600 Watt Gamers Power Supply Unit - OCZ600SXS-UK
CT2KIT25664AA667 4GB kit (2GBx2), 240-pin DIMM (this is the correct memory module i used crucials tool to get it)

I havent even bothered trying to connect anything else to this until i resolve the current problem. I have tried everything, replaced the motherboard tried one memory stick at a time and still nothing. I turn the system on and the fans work everything lights up but my flat screen just goes back into sleep mode and no beeps at all.

(when i had the harddrive fitted it had a red light next to the power button on the case)

I know if there isnt any beeps its failed its "post" and what i got from other forums is it maybe the bios needs upgrading but the asus website is down and how would i update the bios if the screen isnt working!?!?

I have to use the graphics card to put the vga socket in as there isnt a vga slot fitted on the motherboard, i have checked and triple checked the connections everythings fitted fine.

So far i think i can narrow it down to either the cpu the bios or the graphics card but id really could do with some advice.

There may be something in the BIOS that allows the system to not give you a post beep after the first initial successfull post. Don't worry about that too much.

If you are not getting a signal from your video card and you have tried swapping out the memory and or processor, the next logical step is to swap out graphics cards to test that. Or try the card on a known working system to see if it works there.

Call tech support for the card, they may have some other things for you to try.

The only other thing that I can think of is to double check your cables to and from the monitor.

Good luck

1. Is this a new build?

2. Remove the [possibly faulty?] CMOS battery so that the default BIOS configuration settings are used.
You can fit a good/new CMOS battery if/when you succeed in getting the POST to complete.

3. Strip the hardware back to the bare essentials =
PSU, mobo, CPU+heatsink+fan, keyboard, internal speaker

4. Use/connect the on-switch if you think it's OK, otherwise short the pins on the mobo.

5. Ideally the mobo would be out of the case on a non-conducting surface.
This to eliminate the possibility of shorts from the mobo to the case.

6. With no RAM in place, if the POST runs as it aught, and if the internal speaker is functional, and if the BIOS defaults haven't disabled beeps, the POST should sound warning beeps at the failure of the 1st RAM test.
It'll be interesting to see if you get the beeps.
If you do, that indicates that the POST is starting, continues running, and is doing its job properly up to that point, and therefore the connected hardware isn't causing a failure of the POST to function.

7. Then you fit the video card and Startup.
The RAM test failure warning beeps should still be generated.
If they are, the connected video card has not caused a failure of the POST to function.

8. Now fit a single stick of RAM in the 1st slot and Startup.
There should now be no RAM test failure warning beeps.

That's enough for the present time; lets see how that goes.
