How long did you try to clear the CMOS? I would advise trying for 20-30 minutes with a jumper. Please see my method in post #2 of this thread and see if you have any better luck with that.

There is also FDD recovery method's outlined in that same post #2

The error beep you describe is Graphics related, can you try removing the GFX card and reinserting it? Could help?

You could also see if having only one stick of ram in slot one gives you any better results.

If you feel nothing works for you and you must RMA, please let me know and I will give you a last resort link before you have to RMA.

Since you mentioned FDD, Assuming you ALREADY have it connected and set as first boot device, you should be able to blind flash back to the BIOS you was using previously. If you did not already have a FDD connected you will be out of luck using those methods, just a heads up.
