Here is my problem:

My computer initially (shortly after starting up) connects to the internet, but after anything between 5 – 60 minutes randomly stops receiving data. It will still transmit according to the connection status monitor (the bits transmitted number increases) but no more data is shown as coming in. It is as if some conflicting process kicks in and blocks the computer from receiving data. If at this point I disconnect and try to reconnect, the ADSL dial up connection cannot get a response from the remote computer – presumably as all incoming data is blocked.

If I simply log off and log on again the computer will still not connect. If I reboot the computer then it hangs at the “windows is shutting down” screen and I have to power off and power on again (I do wonder if there is some conflict between the computer and the network connection). I can then connect to the internet initially but then the problem recurs.

Here are the solutions I have tried to solve or at least diagnose the problem, without success:

• Used the same modem and modem cable on the same phone line on a different computer (a laptop using Windows 2000) and I do not experience the same problems
• Phoned my ISP, BT, and followed their support suggestions – there is no apparent problem with the line.
• Switched off the firewall, disabled exceptions
• Changed the Modem
• Changed the Modem cable
• Run a virus checker (AVG with the latest updates)
• Run 2 spyware checkers (AdAware and SpyBot) with the latest updates
• Reinstalled Modem drivers
• Deleted USB port devices and restarted to reinstall them
• Installed the latest windows updates
• Deleted the most recent software installs
• Cleared the cache of cookies
• Run a registry cleaner

I am running Windows XP home edition with SP2;
My modem is a BT Voyager USB, connecting through a dial up ADSL connection. There is only a single computer connected – no home network.

I would appreciate any suggestions before I go insane!

Is the modem powered via the USB socket? If so, it could be your PC struggles to power it, and at times the modem overloads the USB sockets causing the internet to hang and the system to act like it does. If possible connect the modem via a powered USB hub to see if this makes any difference.
