Laptop for casual gaming and college?

I have a Lenovo G57 and it's alright on gaming but not great. I can run The Forest on it but it's pretty laggy. I play a good bit of games such as Civ 5 and Terraria. But it would be nice to get a better one that runs games better. It also needs to handle all my college work that'll I need to do on it. My budget is about $400 or less.

Why do the videos load then stop loading on my laptop?

The laptop is a Lenovo G50 with windows 8.1, 8 GB RAM, 1TB HDD and intel core i3 CPU along with other specs.

The problem isn't the internet connection because there are 3 other laptops in the house and videos can play smoothly on them.

I would like to know what the problem is?

Does my laptop supports 1600 RAMs?

So I have learned from a pc diagnostic freeware called CPU-Z that I have a stick of 2gb ddr3 sodimm PC3-12800/1600 RAM.
But when I ran task manager>Performance>Memory, it says there that the speed is only 1333 MHz.
See the screen shots below:
I don't know what my laptop's motherboard is, but I'm using a Lenovo G40 on Windows 8.1 64bit. Thanks. Does my laptop supports 1600 RAMs Added (1). I'm not entirely sure, but I've read somewhere that when a motherboard does not supports 1600, it will just clock down the memory module to a MHz it supports. Is it true?

Is this a decent laptop for the price for a college student?

http://www.bestbuy.com/...9091398274

It has Windows 8.1, Intel 4th generation i5 processor, 4gb RAM, 500gb hard drive (apparently it's a hybrid hard drive not sure if that makes it better or not), 1920 x 1080 display.

I think the screen size is perfect, and I like the ability of having the 2-in-one style, but do you think that it's very useful/worth the price? With a discount I have i'd be able to get it for around $700… Does that sound like a good price for this laptop? I'm looking for it to be portable and good to take to college for writing notes, papers, streaming movies and music, etc (not a design major where i'd be using Photoshop all the time and i'm not a heavy gamer either). It has a better display/screen that most of the other laptops i've looked at. I know there are laptops with 6gb and 8gb of RAM, but 4gb seems like the most common and i'm not running that heavy programs/games so wouldn't it be good? The only thing is that it only has 2 USB ports but I can always get a usb hub or something for that. What do you think?

Can pictures ever be retrieved from my dead laptop?

I have a Lenovo IdeaPad S10. It won't charge even after a new battery and power adapter so I'm assuming the charging port is busted. It's been drained of battery life for about 4 months, and I was never able to back up my very precious photos/videos. As of now I'm broke and can't bring it to a computer store. In the future, whether it be a year or 10 years, would I be able to do something, ANYTHING, to retrieve those files?
