Hi NiteStryker,

Are you able to connect to the internet by booting your computer in Safe mode with networking?
To boot the computer using the option: Safe mode with Networking
1. Use F8 while restarting the computer.
2. Select Safe mode with networking under Windows Advanced Boot Options and hit Enter.

Login to windows in Safe mode and check if you’re able to connect to the Internet using Internet Explorer.

If you’re able to connect to the Internet, then try performing a clean boot to eliminate any conflicting software.

How to troubleshoot a problem by performing a clean boot in Windows Vista
Note: Do not forget to put the computer back to normal startup once you’re able to get rid of the conflicting software.

If you’re not able to connect to the Internet in Safe mode with Networking, then I would suggest you to re-register the following dll files in Safe mode itself.

1. Click the Start menu, in Start Search, type "cmd" (without quotation marks), right-click on cmd.exe and click Run as Administrator.
2. Run the following commands pressing Enter after each one.
regsvr32 Netshell.dll
regsvr32 netcfgx.dll
regsvr32 Netman.dll

3. Once all the dll files are re-registered, check if you’re able to connect to the Internet by booting the computer back to the normal mode.

If this did not work, then you need to remove all the network adapters in the Device Manager and re-install the latest driver for your Network Card.
