I have a HP Pavilion computer running Windows Vista with a Nvidia nForce networking controller. The pages will stop loading after a while and will seem frozen. If I delete the network device driver and reinstall it it will start working again for a while. I have to do this several times a day. Any ideas?

Your Nvidia controller may have built-in firewall that is turned on by default. Check the model of the chip and google info on it. Once you confirm it is the case, you can download a program that can change settings on the controller firewall
