I have Windows Vista. And I used Opera web browser but every minute it said the message that it was not responding and an error console popped out every few minutes. Then I used Firefox it also giving me problems now all the browsers including Internet explorer occasionally give me the message that the server timed out and no website appears and usually comes out at midnight for some reason and lasts for a long time but it usually happens all the day for some minutes . But my wireless Xbox Live connection works. Could this be my computers wireless receiver. I have a recent computer. I am aware I have run ons.

Vista isn't friendly with open-source programs, check that the version you are using supports vista, but most may have joined the bad vista movement because of these difficulties.
