3 blinks (3 beeps) On-off (1.0 second each) three times, then 2.5-second pause (off). The pattern repeats until the computer is powered off. This is blinking code for memory error.
Try using just one memory module at a time, swapping it between the upper and lower memory slots.
Hope this will help
I was using a 1.5V regular SODIMM memory(DDR3). Swapped it out with 1.3V per the specified spec (DDR3L). It works now. Thanks mate.
