Video Beep Error

I have a video beep error from my motherboard.  The screen remains blank and in standby mode.  The monitor is connected to the video card through a VGA to DVI adaptor and goes straight to standby mode when it is plugged into the adaptor (when its not plugged into the video card even).  I've tried 3 monitors and all with the same result.

I bought a eVGA 7600GT KO and had this problem so I RMA'd it for refund and bought an MSI 7900GT.  Both cards got/get the video beep error.  I RMA'd my first motherboard for a replacement (absolutly no POST) and managed to get atleast a beep error from  my current one ( Gigabyte GA-M55SLI-S4 Socket AM2 NVIDIA nForce4 SLI ATX AMD Motherboard).

My power supply is a Rosewill RP550V2-D-SL: +3.3V 30A, +5V 50A, +12V1 18A, +12V2 18A, -12V 1.0A 12W, +5V 2.5A 12.5W

My RAM is:  gigaram 2GB (2 x 1GB) 240-Pin DDR2 SDRAM Unbuffered DDR2 667 (PC2 5300) Dual Channel Kit

The exact beep code that the motherboard spits out is:

Click - pause - Long Beep - pause - click, click, Long Beep - Pause - (Continuously repeats pause, Click, Click, Long Beep)

It is an Awards Bios.  I can't check the current version because I get no screen...

Have you tried removing the video card (and all other perherprials) and seeing if the motherboard POSTs? That will help in narrowing down the problem.

http://www.bioscentral.com/beepcodes/awardbeep.htm says that two short, one long for an Award BIOS means a video card problem, so it's definitely sounding like that's the culprit. Try the above, and if it POSTs without the video card, that confirms it.

I tried all of this and it will still POST.

Can an under powered video card won't give a video beep error?

Saging my crappy mastery of my native language.

Can an under powered video card cause a video beep error?

The 7900 would require a molex power connector. Do you have that plugged in?

My power supply has a 6-pin connector and the 7900 came with a molex (requires 2) to 6-pin convertor.  I have tried using both of these with no change in the boot results.

The motherboard has a molex connection to supply the PCIe x16 slots with additional power.  The only diffenece between this being plugged/unpluggeed is that the video card fan seems to be louder (faster I'm assuming) when its plugged in.  The other molex and floppy power connection aren't plugged into anything.

Think I should volt test the molex connections coming from the PSU and plug the highest Voltage one in?
