laptop beeping sound

my laptop is an inspiron 3420

sometimes/ not very frequently my computer has been giving off a beeping sound. its been 2 quick beeps. i have researched it a bit and found out that it has to do with the RAM (im not really experienced with these tech terms). it just happens randomly....

in addition, there is a single quick beep that i hear as well....

can anyone tell me what exactly is the problem and how i can fix it immediately?
