XP Hangs

[dondon]

I have Windows XP PRO with all critical updates.Every thing was fine but all of a sudden whenever I connect to the internet the computer hangs and the only way out of it is to reset the computer.
I tried uninstalling and reinstalling the network card and modem & USB but to no avail.So then I tried to install a ISDN external USB Modem but it totally hangs again during the installation.Does anyone have any ideas?

Have you log in your event logs to see if there any errors listed? If so what are they?
