What OS are you using?
Perform the following procedures, if you have not done so already:
Scan for and remove any of the following:
viruses, spy/adware.
Remove temp files,etc.
e.g. If Windows XP, go to Start > All Programs > Accessories > System Tools > Disk Cleanup > OK. Under "Files to delete" place a check mark beside each item except "Compress old files" and "Catalogue files for content indexer." Click OK > Yes.
Then go to Start > Control Panel > Internet Options. On the General tab under Temporary Internet Files click on Delete files > OK. Under History click on Clear History > OK. Also, while in Internet Options go to the Security tab and click on Default > Apply OK.
Restart the computer.
If you are still getting "The page cannot be displayed" download, install and run WinSock XP Fix 1.2. Before running this program I suggest first creating a System Restore point in the event that you are not entirely happy with the results, as you [may] find that some browser addons may need to be reinstalled.
Restart the computer and see if you are still getting "The page cannot be displayed.
Hope something here is helpful.

No matter what I try, IE 6.0 won't let me go to google.com, I get the famous "Page cannot be displayed" screen.
