Hi all. I bought this Macbook pro around 2 years ago for college work, and this is the first major problem I've had with it. A few days ago I had numerous tabs open on Google Chrome whilst Spotify and PowerPoint were open. Randomly whilst watching a video my computer crashed and since hasn't worked properly. At first it wouldn't come on, it would get to the stage where you put your password in and freeze indefinitely. Now it comes on but I'm unable to use it... I always have the spinning rainbow loading circle (haven't got a clue what it's called) but nothing works properly. I've added all my desktop items to one folder as I've been told this could help speed up my mac, but I haven't been able to try anything else as it literally won't work. I can't even empty my trash haha. Any tips or advice would be appreciated! I really need this fixed soon as I have assignments due in and can't afford to take it to the apple store Thank you!
