Explain where exactly the bios is hanging at, ie. the message on the screen. Long beeps for me usually indicates the gates for the system ram aren't properly closed. Check the gates for the ram. If the gates seem ok, then try goofing with the ram placement. Try one ram only in the primary gate. If that doesn't work, try the other ram in the primary gate. If that doesn't work then get some ram from another computer (yours or a friends) and stick it in the board. IF the computer works then the ram you have is either defective, not supported, or requires lower default setting in the bios in order to work (same as being defective anyways). If the computer doesn't work with the other ram then its either a defective bios, or a defective ram gate, either way you may need to RMA the mother board. Also try sticking the ram you have in other computers and see if they post. Also if both of the ram work in the primary gate but won't work in either of the secondary ram gates then your auxilary gates are defective, RMA the board.
TRY all of this and you should be able to figure out the problem really quickly. Just be systematic and logical in your troubleshooting and you should be able to figure out the problem easily.
