Hi, you have duplicate appends going. Suggest you close one. Here's answer from other post.
The three beeps are beep codes. The MB is trying to tell you something.

3 beeps? That's bad memory.
" Reseat the memory.
Make sure that the contacts on the memory and the socket are clean.
Try removing one bank of memory modules at a time. (Some systems can require a memory module in Bank 0.)
Try using memory modules from the same manufacturer with the same part number and speed.
Check for a faulty memory module by trying the memory in a known good system."
good news. If it turns out to me memory, memory is currently really cheap.
