Mar 15, 2016 12:34 AM in response to Chrisp_cremeby KimUserName,- 3 successive tones, a 5 second pause (repeating): This indicates RAM does not pass a data integrity check.
See the following help file: About Mac computer startup tones - Apple Support
What did they tell you when you took our computer to the Genius Bar?
What type of RAM did you use?
Macs are very fussy about what kind of RAM you are using.
You can install either OWC OWC memory or crucial Crusial Mac memory memory.

Mar 15, 2016 3:41 AM in response to Chrisp_cremeby OGELTHORPE,I am surprised that the technicians at the genius bar were not able to resolve the issue.
How many sets of RAM do you have? If you replaced the original RAM, are the specifications of the new RAM: 204-pin PC3-12800 (1600 MHz) DDR3 SO-DIMM?
First try this; clean the contacts and install one module only in one slot and then in the other slot. Repeat this with the other module. You are testing to see if one module or one slot is faulty. (make certain that you seat the modules properly)
Post back the results.
Ciao.
