Okay, so i one day i tried to get on the internet, but every browser i tried couldn't connect. The browsers i use are IE, Firefox, and Chrome. I can connect to the internet through MSN messenger, Limerwire, and Skype. I have been told to reinstall my OS, but i dont know how to do that and am hoping someone here knows another way to fix this problem. I use Windows XP. If i have to reinstall OS can someone give me a guide for a beginner on how to do that.
