What really mean one long and three short beeps on the A8N32-SLI Deluxe BIOS?

I suppose nobady had this problem before.

I am trying to help a friend,he is getting at start up one long and three short beeps on his A8N32-SLI Deluxe.

According to this,

One long and three short beeps is a memory error.

But when i remove all the Ram from my system i get one long and two short beeps.

So,if one long and two short beeps is a memory error,then one long and three short beeps what is it mean?A video error?

You may ask why i don't remove the video card to see what beeps i will get.

My 8800GTX just fit in the case and to remove it i have to remove all HDs,my sound card,plus two fans i have in there.

If anybady with an A8N32-SLI Deluxe can help we really appreciate it,if not then i have to remove my graphics.

Thanks.
