Dell 8700 Windows 7. Certain program pages will not access internet. Not all but a handful when you select them from within will not open a web page. Old 8300 Win 7 has no problem with same programs and has same virus program installed with same effect when virus disabled in 8700 Tried MSConfig without any luck. Believe it is in hardware specifically internet card permissions-did upgrade card from dell.com. I believe it has something to do with network access-normal internet works fine and both PCs attached to same wireless router-it has to be something inside 8700. Any suggestions?
