I bought new RAM from ifixit for my MacBook, still not working.

MacBook Pro 13" Unibody Early 2012

so the original ram my macbook are not working, how sometimes my computer freezes and does rainbow vertical lines; when sometimes i open it it does three beeps and i will turn it off, and probably can use it the next day.

So i found out that it was the RAM, i believed it because when i opened computer and took off one of the ram, it'll work. And i keep doing this over and over. Then i bought new "used" ram from here. I plugged them in, and believed that it'll work properly now that i wont get any verticle rainbow lines and beeps. It worked perfectly fine yesterday. And then, i opened it in class and i heard three beeps again. My computer wont turn on.

Its embarrasing bc ppl are looking at me wondering whats that sound. Can any one help me please.

Please give us the last four figures of your serial number. There was no early 2012 MBP. Let's correctly identify your machine, then tell us the exact RAM you installed.

If you remove the stick you believe is defective does the macbook boot and run fine?

I'm pretty sure it's the RAM because i've googled up why am i getting three beeps. I took the old ones off and placed them back and worked fine. But after a day, it'll do the beeps again. Decided I should get new RAM, plugged them in, worked fine yesterday. Then does the three beeps the next day.
