Hello, please i will like to knw if upgrading my ram will increase the performance because i'm using a 1gb ram wit 500gb HDD and my computer is kinda slow, should i upgrade the ram or reload the os?

Upgrading the RAM will surely improve your computer performance. But you must first establish why the computer is slow. Maybe what it needs is maintenance. You know your computer, will reloading the OS make it run faster than it is now? Or you want to do a hardware upgrade for better overall performance. What is the percentage of free space and file fragmentation? When did you last do defragmentation? Have used the check disk utility in the last 21 days? All these questions will help you get to know the status of the health of your computer.

first of all I need to know to model of your laptop because some laptops require lower ram to work {512mb}
While some require larger r.a.m
