Hey Mitchell,
Formatting your HDD
I think you may be having a little bit of confusion here with your operating system. Are you attempting to format your HDD from within Windows? If so, you will run into quite a bit of trouble with that. Windows is relying on it's installation to run and you are trying to wipe out the installation while it's running.
If you want to format your HDD, first realize you will have to reinstall Windows 7 and you will lose your data.
Simply insert the Windows 7 CD into your computer and boot into the installation. During the installation, you will see a screen that asks where you want to install windows. On this screen, you can click Advanced and you will get the option to Erase (format) a drive.

Internet Connection
Set your connection to receive settings via DHCP
As far as your internet is concerned, I'd first make sure that you have your computer set to receive it's connection via DHCP. To do this, you will go to
Control Panel -> Network and Sharing Center -> Change adapter settings.
From here,
right click Local Area Connection and click
Properties. (If prompted for Administrator rights, click Yes.)
Single left click Internet Protocol Version 4 (TCP/IPv4) and
click Properties. Make sure that both
"Obtain an IP address automatically" and "
Obtain DNS server address automatically" are checked. If they are not, go ahead and test your internet connection again.
It should look like this:
If it does look like the image above, then go to another computer on the network or a device and
open command prompt (start -> type "CMD" -> hit enter) and type:
ipconfig and hit enter again. (if you have an android device, you can download an IPCONFIG from the Google Play Store, such as this one
here.) Write down this computer or device's
IPv4 Address, Subnet Mask and Default Gateway that show up under Local Area Network Connection and return to your other computer.
Information to copy down:
Follow the steps to get to your Internet Protocol Version 4 (TCP/IPv4) settings mentioned above again. This time, you will click the radio button for "
Use the following IP address:" Fill in the IP address you copied down, but change the last octet. For example:
Other computer's IP: 192.168.1.154
IP to type in to your computer: 192.168.1.156
For the DNS, you can use Google's DNS:
8.8.8.8
8.8.4.4
It will look something like this, except with your IP addresses and masks:
(You may want to try pinging the new IP address from your other computer to verify it's not already taken. To do this, just type
ping and then the IP address. In our case, it would look like this:
ping 192.168.1.156
If it times out and no response is received, then you can safely set your computer to this IP address.)
Verification an IP isn't in use:
Then enter the Subnet mask and Default gateway exactly as you copied it down.
Test your connection again.
Let me know if you have any success with this.
