help Internet access

Just built the computer I listed a few days ago on this forum. It booted, I installed Windows7 without a hitch and I'm very pleased with it... I just have a few questions.

I haven't installed any drivers for anything, I cannot connect to the internet through wireless or hardline connections, and my monitor is being a punk.

I didn't install a wireless network card, it slipped my mind in the original build and I hoped it might be built in somehow to something I installed. I figured the hardline would work, it only made sense... since it doesn't, what am I missing or what have I messed up?

The monitor displays my max resolution but it keeps certain margins on the sides, top and bottom. It's like the monitor decided to center my display and only allow me to use the center. In the monitor settings, there is an Aspect Ratio option but it is greyed out. I've tampered with every other setting to try and unlock the Aspect Ratio, but it's still greyed out.

I suspect I am missing something important. Never built before and I followed a video from Newegg that correctly assembled everything... I just don't see where the problem is.

I'm in the process of moving cross-country, so I've mistakenly packed my box full of the manuals and warranties and didn't label it to find it again. I figure I can download the drivers to my flash drive and install them that way, but I don't know what all requires a driver. So far I know the graphics card and motherboard, since you've mentioned them. Any others of necessity at this point?

Okay, deeper question - I'm on the ASRock page to download drivers and there are so many that I don't even know where to start. I thought it was a simple single driver for the motherboard. What do I actually need first? Once I have internet capability, I can go through a check to update and provide any missing drivers.

This is the list I'm looking at. I see no driver named LAN, but this is what falls under my MoBo's list

Learned the hard way that monitors don't come with speakers all the time, that power supplies can be modular and I have 852936723 cables I don't need, and that I need a network card to receive wireless internet.

Posting from the computer I built though and everything is working properly now. I'm very content and I'm glad I had your help! Much appreciated,
