inspiron 7447 looks great, but what about the price?

Hello all!

Okay, so recently my laptop just died all of a sudden. I was somewhat expecting it because it was showing signs of faultiness here and there
(FYI, its a Toshiba laptop with Windows Vista)

So obviously, I'd want to get a new one. I'm not good with technology nor do I keep up to date with these kinds of stuff so I was wondering whether anyone could recommend me some ideas/brands to look at?
Here are my criteria:

1. Laptop (Portable, & I dont have space for a computer)

2. Preferably Windows (cause I think Macs are overpriced if I'm not mistaken? Also, I'm very used to Windows)

3. It needs to at least be able to play Sims 4 (and/or some mainstream Steam games like L4D2) smoothly

4. A reliable brand(?) that lasts long (I don't expect it to last forever, but my previous laptop honestly has problems ever since the 2nd or 3rd month I had it)

5. Cheap (I'm a student. I'm willing to spend for this, but in no way I'm going to spend, say, for an "Alienware" or whatchamacall it)
I'm sorry if I sound really stupid, but as you can tell, I don't know much about computers/laptops! So any form of help would be nice!

Thank you!
