I'm having a terrible time with one win 7 32 bit computer on my home network. All other devices (about 12) work fine, other windows 7 pc works fine, ADSL router and Cisco switch work fine. This one Dell Vostro 430 with a cable into the network worked fine for 2 years. Overnight it can't connect to local network with its DHCP settings and if I change to static ip it still can't browse the internet. However I can ping external addresses by IP address only. If I ping google.com eg it cannot find the host. What is really confusing is the "Ping Statistics for " response contains neither the name or the address but instead random characters... ie ãäý¶è$5ÿÿÏ this changes every time. all other devices on the same network resolve IP adresses to their fully qualified domain name.
I have been through loads of sites and support, flushing dns, flushing IP, restoring the pc to a previous working point, changing the network cable and port, installing a USB wireless key (which works on this pc), manually configuring IP addresses, reseting the IP and WINSOCKs with Netsh commands, I ran anti malware, Combofix,virus checkers (zone alarm) all found nothing, I booted into a linux instance but still couldn't browse the net, I cabled two pcs back to back and could ping each other from each other then restored the cable to the bad Dell I still didn't get a DHCP address but with manual IP, gateway and DNS I could ping 8.8.8.8 but not browse.
I have run out of ideas....anyone help
Oh it's win 7 professional and there may be a few more things I've done but forgotten in the post above
Obviously changed drivers on NIC, and installed drivers for the wireless USB NIC,
