Chosen Solution

I have this macbook air 2015 with 4 GB of RAM and 256GB of SSD, the device is having a very slow performance. On start up, I tried to open chrome and it opens with blank window and the spinning-loading-thing. Most of the times when I am trying to open Youtube or sites that contain video-based Ads, the macbook suddenly the mac freezes and I have to do the force shut down. By any chance, is my SSD the problem here?

@bypasser11 - Did you read my update here: My MacBook require PRAM reset for every boot checking the drive. Its also best to keep things in one question Vs spinning off a second question which is still active.
