This may depend on if these are short beeps or not. 2 short beeps usually indicates a memory problem. Have you recently installed new memory modules or otherwise removed and replaced the same memory modules?
Since you had no picture on the monitor, you might have a parity error in your first 64K of memory. First check your memory modules. Reseat them and reboot. If this doesn't do it, one or more of the memory chips may be bad. You can try switching the first and second banks memory chips. First banks are the memory banks that your CPU finds its first 64K of base memory in. You'll need to consult your motherboard manual to see which bank is first since this is not always left to right as you might think they would be.
