The price of the machine if out of warranty means you replace it. https://www.google.com/search?q=X553sa finds them at 207 and up.
You didn't tell if this was your first time at replacing RAM. Have someone that has done this check your work.
YOU MIGHT BE IN LUCK. https://www.asus.com/support/Warranty/3/627/0/2/mFvsJaDKAQzrbQhm/ and the PDF there notes 24 month warranty. CHECK YOUR WARRANTY but be sure it is in stock condition.
I have a asus laptop X553sa And upgraded the ram and it will not boot up. I've tried the hard reset and removing the battery. Still nothing works. No lights fan screen. I even put the old ram back still and still nothing.
