I had the PSU fail on my PC, was working perfectly one evening, would not start the next day. Anyway I have replaced the PSU and it is working just fine again except… I cannot now access the internet via Web browser. Outlook e-mail is fine, I can ping the DNS servers OK.

My connection is via a D-Link router which is working just fine as I am accessing the internet on my wifes’s’s laptop wirelessly using the same router.

When I click on Firefox I get the message.

The connection to the server was reset while the page was being loaded
The network link was interrupted while negotiating a connection.

Not hugely helpful!

Using IE I get the standard page not available message, but if I run the XP network check it shows these messages
Windows cannot connect using HTTP, HTPS or FTP
Check the firewall settings for HTTP (Port80) HTTPS Port (Port 443) and FTP (Port 21)

I use Black Ice firewall software, but turning it off completely does not make any difference so I don’t think the problem lies with the firewall.

Any suggestions please?
