Hello! The three beeps likely signify a RAM issue. On your model Mac, the RAM is soldered the logic board. So, I would start by performing an NVRAM reset (Command-Option-P-R) and see if this fixes the issue. If not, its possible you will need to replace the logic board on your machine. Ensure that everything is properly seated, attempt to reset the NVRAM, and take it from there.
