Need some help please, typing this from someone else's laptop.
Today when I came back from school, I found that I could no longer surf the net. I called my ISP tech support, worked with them, and we came to the conclusion that the problem is in my PC, not the internet connection.
Actually, I'm connected to the internet with this laptop through my own modem, so it works.
I run ESET Smart Security (ran the AV and it came out clean).
Win XP SP2
The only thing that I remember doing that could get me infected was accepting someone into my MSN messenger, which turned out to be some kind of SPAM (thought it was someone with a weird address from school), and when I realized of my mistake, I erased the contact and blocked it. Still it could send me messages, and other invitations continued to pop up in my MSN.
No, I don't have System Restore activated.
And I'm afraid that this could be the same thing that happened to my mom's HP laptop, its network card fried. However, I did ping to 127.0.0.1, and all the packets were received just fine, so I'm guessing my card is alive.
Any of you guys can think of a solution for my problem?
Thanks!

Hmmm. the only thing i can think of it check cables. Did you have a pet that could of bit the cord and opened it up. The other thing i do sometimes is unplug modem router etc. and leave it of for like a minute or two.

Reformat/reinstall. Get an external hard drive and image your clean install.

Can you ping some external site (e.g. deltava.org or hotmail, google etc.)
There are a variety of reasons where a internet connection can stop working or give the perception to do so.
Looks to me like a malware infection that came from the link and that needs to be cleaned up. What antivirus on your machine and is it updated?
Do these things and let us know:
1. Check task manager for processes you do not recognize. If in doubt look them up one by one on google and kill them one by one and see what happens.
2. Go to C:\windows\system32\drivers\etc\hosts and check if there are some superfluous entries you do not recognize other than a localhost pointing to 127.0.0.1. If yes, delete them and try again.
3. Clean up temp files (Documents and settings & C:\windows\temp). Clean up c:\windows\prefetch.
4. Once the modem connection is established do a 'ping www.google.com' and 'nslookup www.google.come' (or some other site) and what do you see.
5. From the IP address given as a result of the above commands, if you directly type into the browsers address bar, are you able to reach the site.
Also, somehow I was not able to understand the pinging of 127.0.0.1. This would always give you 100% success even if you pull out all the cables (except power).
Email me (through the other computer) if this does not get you going and we can take it further.

Hi there.
I tried my PC again today, and internet DID work. But it only worked with some sites: gmail, google, youtube, college site, and MSN messenger.
But Deltava.org, VATSIM.net, VATMEX.com and many other sites still appear as unreachable.
Gurmeet:
1) All the processes are normal, not even one that I hadn't seen there or shouldn't be there.
2) No entries for 127 were found. It's normal.
3) Temp files and prefetch are empty, still no luck.
4)
PING TO WWW.GOOGLE.COM: works. All 4 packets sent and received.
PING TO WWW.VATSIM.NET: does NOT work: "The request to ping could not find the host www.vatsim.net"
NSLOOKUP to WWW.GOOGLE.COM: "Could not find the name of the server for the address 10.1.2.116: non-existen domain".
These websites are up and running (checked them from this laptop using my every-day modem).
5) I can reach the sites I can ping. I don't have IP addresses for those I can't ping, though, so no way to try.
About the 127.0.0.1 ping... see, I took CISCO 2 (CCNA) at college, and the teacher told us that one way to check if your network card is faulty or fried, was to ping the computer to 127.0.0.1, and this also proves that your TCP/IP protocol is up.
I'm emailing this to you too, Gurmeet.
Thanks for the help. I'm just trying to avoid a reinstall, as I don'0t have time for it... still this is a 5 year-old Windows install, it must be corrupted like heck!

UPDATE:
VATSIM site works well by inputting the IP address directly into the address bar in my navigator. Doesn't work by typing "www.vatsim.net" though.
DNS problem then?

Yes. This is what looks like.
Do a "ipconfig /release *Con*" followed by a "ipconfig /flushdns" and then 'ipconfig /renew" and this should fix it.
Just check that you get valid DNS servers and are able to reach them using ping.

David, I'm having the same problem. However my problem is because my drivers for my ethernet, multimedia audio, and video controllers, and my SM bus controller all got deleted. It took some work, but I managed to track down a system recovery disk for my puter.

Thanks for the input Phillip! I did reinstall the drivers for the ethernet, yet it didn't solve the problem.
I've been trying to figure it out with Gurmeet's help, and we came to the conclusion that it's most likely a malware problem, even though not a single program has detected anything in my computer (ESET, Spybot, Lavasoft...)
Right now, the internet's working normally.
The problem was - the IP was changing very drastically. My normal IP is in the 201.X.X.X range, but when it [somehow] changes to 182.X.X.X (a whole different subnet) my internet goes nuts.
My ISP claims it's not their fault...
