Strange network/internet connection problem

System: Compaq (don't know model, latest one however, 4Gb ram, nVidia G100 graphics Intel c2d 2.4Ghz).
OS: Vista Home Premium

When did the error occur? Today, started downloading a file via Torrent (ReBirth), told uTorrent to shut down system when done downloading. Did so. Restarted system and the error occured:

Can not connect to the internet. Have tried bypassing the router directly to the cable modem. The connection does work in failsafe mode. I first thought it was network card/system files related. But in Failsafe it works, so what does that mean?

Please help me if you know what to do, I'm not good at all in Vista OS.

Thankful for any replies given..

First thing i would do is some basic diagnosis:

Open a command prompt (cmd.exe)

From the command prompt type ipconfig (this will show you your PCs IP address, default gateway, DNS settings etc)
Now from command prompt type ping <ip address of your PC>
Now try ping <ip address of default gateway>
Now try ping <ip address of DNS>

If you can post back your result (copy/paste maybe) that will help point out where the issue lies.

If it is working in safe mode, then there must be something starting up that is killing the connection. Do what Iggster says first though.

utorrent doesn't have the half open connections issue because it limits itself to 10.

The router might have been overloaded, but then the torrent wouldn't have finished, and utorrent wouldn't have shut down the computer.

Thanks, I'll try what you said Iggster.
I have restarted both modem and router, there is another computer connected to the router - and that one is ok.. (strange?).
I'll check back here later with the results.

Thanks for all the help. It seemed to be a program that was installed (now uninstalled) and everything is working as it should. Something had even disabled windows firewall and Windows Defender (!!).
