Whats wrong with my computer?

I have an Asus laptop

2 years old

While on it runs fine

When I bump the backscreen while the power is on the screen breaks (like how old tvs looked "snowy")

Now whenever I close the screen (to put it into sleep) it won't come back on: The screen goes blank but it says the backlight and connection and power remain on. I tap any letter key and there's a ding sound but otherwise the keyboard loses function. There's nothing I can do when this happens so I have to do a hard shut off. This has happened a few times already.

I'm looking for serious answers. I know the best thing I could do is to take it to an expert or to BestBuy but I'm looking for some advice on here first.

Also my biggest concern is losing my photo and word documents so I was going to look for a backup. I have an external hard drive but I was recently recommended to also use a Cloud service. If you have advice on which Cloud (Google, Microsoft, etc) I should or shouldn't use thatd be appreciated.

Thanks in advance.
