Laptop for an incoming college freshman?

I'm heading off to college this fall and am currently looking for a laptop to bring with. My parents are going to help pay, but I'd like to stay under $500 if possible. As far as sizes, I'd prefer a bigger screen, but don't want to go over like a 15.6". I have some time before I really need to get it so I'd like to do my research and get the right one. I'm just having a hard time narowwing it down to a good student laptop. Any and all suggestions would be great!

Will this RAM work in my laptop? (Lenovo G505S)?

This is the RAM I'd like to buy - http://www.ebuyer.com/544307-crucial-8gb-ddr3-1866mhz-ballistix-sport-bls2c4g3n18aes4ceu

I own a Lenovo G505S.

I don't feel like my graphics card is working properly. Am I doing something wrong?

I got a brand new laptop from Lenovo that was designed for gaming. However, this computer runs games poorly at best. I'm working with a Lenovo y40-80 laptop with an AMD Radeon r9 275 graphics card. I was expecting this thing to be great, even in the comments for the thing, it said it would run Bioshock Infinite smoothly just not on highest settings. I can't even run Bioshock Infinite on the lowest settings without getting serious lag. I did everything from switching the computer settings around for higher performance to making sure AMD Radeon is running my games. And it is. Same thing happened for Battlefield Bad Company 2. My Dell Inspiron could run that game better than this thing and it had an hd 3000 graphics card! So what is the problem with my computer am I doing something wrong or is it essentially broken?

i have the lenovo g50 - 70 laptop.

8.1 update load and install time: why is it going so slow & taking forever?

When I first bought my Lenovo Yoga 13 and I installed windows 8.1 it ran super quickly…2 years later, it is taking forever to load onto my laptop. Is it just because it's getting old or is there something up with Windows itself?

Added (1). When I go to my Settings, the update will be doing its thing and loading but it'll stop and freeze right in the middle of things and then start over when it never did this before. What gives?! Is my laptop just getting old or is Windows becoming outdated and super slow because of time passing? It's frustrating.
