Respuesta a "I'm upgrading my 2GB Ram to 8GB but I'm nit sure what to get"No the Asus X553SA uses DDR3L PC3L wich is a special kind of DDR3 ram that has a low voltage(The L stands for Low) so you will need DDR3L PC3L ram instead. Here is it on NewEgg (https://www.newegg.com/p/pl?d=ddr3L+pc3l )
Respuesta a "PS3 not reading game discs. Not blu ray drive"You could try to clean the lazer with rubbing alcohol but there is also a chance that you will need to replace the Blu ray lazer. Tho depending on the model you may need to open it(super slim doesn’t require opening it but the rest do).
