My daughter got some sort of virus on her computer, by the time she told me about it she had a blue screen and Windows would not boot.

She was running XP Pro with all the current updates.

I formatted and reinstalled XP Pro, using the long, not fast, format option (our version is pre SP2) and tried to connect to the Internet to get all the service packs and updates, but cannot connect to the Internet.

I could connect to the wireless router with a strong signal but not to the Internet. I tried to repair the connection but could not renew the IP address.

We have 5 other computers connecting to the same router, so bad a router is not the problem. The computer is still sitting in the same location as it was prior to this mess, so location in relation to the router is also not the issue.

I tried setting a fixed IP, still could not connect.

I have changed out the wireless card (with the proper drivers) using one from another computer that is working fine. Still can't get an IP.

I ran winsockXPfix.exe.

Then, in desperation, I installed Windows 7 Ultimate. Same problem, can't get an IP assigned and setting a fixed IP doesn't work either.

Also, no firewall or anti virus are currently installed (except whatever Windows 7 installs, but I checked it when I still had XP Pro installed), so they can't be blocking.

What I am wondering is if the virus possibly shut some ports or did some mischief that is not even fixable with a format and clean install.

Tools, I have at my disposal:
USB flash drive for transferring files
CD/DVD burner to transfer bigger files

I am not worried about reinstalling an OS, computer has no files to save.

Please advise, I could really use some help with this one!

Hello ,try these if no luck I'll move yo to another forum.

Try this--open control, internet options, connections tab, lan settings, uncheck the box next to "use proxy...."

OR
Go to Start ... Run and type in cmd
A dos Window will appear.
Type in the dos window: netsh winsock reset
Click on the enter key.

Reboot your system to complete the process.

OR
For Windows 2K/XP
Please go to Start -> Control Panel, and choose Network Connections. Then right click on your default connection, usually Local Area Connection or Dial-up Connection if you are using Dial-up, and left click on properties. Double-click on the Internet Protocol (TCP/IP) item and select the radio button that says Obtain DNS servers automatically. Click OK twice, and restart your computer.

Hello as you have re formatted, Malware should be gone. I will move this to networking for others to see.

What is installed now? XP? or 7?

At a command prompt, when you type ipconfig /all and hit Enter, what is shown? If you have 7 installed it'll be the IPv4 that I am interested in.

And you are connecting wireless? Have you tried wired?

Hope this helps thumbup.gif
