3 short Base 64K memory failure A memory failure has occurred in the first 64K of RAM.
I don't see a listing for 3 long beeps.
Typically 3 beeps is an indication of a RAM issue in general. If you're using more than one DIMM, try removing all of them except for one, and try swapping that DIMM or moving it to different sockets to narrow down what the problem is. (Bad DIMM, bad socket, etc.)
