The beep codes match AMI bios error codes and ibm error codes. In both cases it is saying memory failure. For AMI it is saying total memory failure therefore system will not start and no error message will display. For IBM it says Video memory has failed video adapter has failed.
First try and change the memory either by reseating or changing the modules positions. Next step is to replace memory if the first step failed to give results. Last step is replace video card or memory on video card if card has replaceable memory. You may elect to have video card checked in a known good system to rule out card failure.
