Repeating long beeps or a continuous beep can also indicate bad ram, bad keyboard, or a shorted motherboard. I'd look at the RAM first as that was what set this all off to start with. Make sure the RAM is seated firmly in the slots, that it is the correct type for your motherboard, and that it is in working order.
Then check ALL of the cables from the power supply to the motherboard and to the drives.
Try the machine with a different keyboard.
I have had motherboards "crack" when installing RAM. This does not necesarily mean that the board is cracked, but that a trace within the board cracked and is either shorting to another trace, or is simply not allowing a circuit to be completed.
Unless it is the RAM, the keyboard, or a cable issue, it is probably not something you'll be able to repair yourself.
