So there I was, trying to install the driver for my XBOX 360 wireless receiver. Some bloke off another forum told me that I needed to uninstall the driver for the unrecognizable device that was my wireless receiver. I did so and proceeded to restart my computer. It booted up and I tried to open iTunes and then noticed my volume bar icon had a red cross through it. Clicking on it only brought me too a "Attempting to Fix" progress bar which inevitably failed. Tried to open my web browser to look for a solution and had a "Could not contact DNS server spat in my face. I tried to open the Network and Sharing Centre but it told me that that feature was currently unavailable. Tried running a virus scan in AVG but it just didn't wan't to happen as nothing happened when I tried to scan. Eventually decided to screw it and just run a system restore but ironically (andvery frustratingly) it brought me an error. Now my first guess is that I need to reinstall windows 7 but I don't currently know where my CDs are and would like to know my options before taking that plunge. Thank you very much for your time, and thank you in advance for those with a solution.
