I installed Windows 7 on a new hard drive and did all the updating etc. At some point it has developed a problem whereby I cant see the internet on any browser. Internet security is at default levels. Diagnostics says that the computer is correctly configured but the device or resource (DNS server) is not responding. Somehow I'm skeptical as the iMAC, Ipad and laptop are all connecting okay. The PC is hard wired to the router, but so is the iMac.
Sometimes get text instead of a web page.
