All I can figure out from your ongoing sentence is that your Favorites shortcuts are out of whack.

 

how to solve this probelm?

so how can i fix this problem????????????

 

I have just noticed this type of error on my parents computer.
They were having a problem accessing any websites. After a little digging, I found that somehow, they had forced a DNS server in their network settings. No one is sure how this got there.

After I set their DNS settings back to OBTAIN, I was able to get back on the internet, but google will not come up. It appears I can get to all websites but google. Also when I go to Yahoo, I can access the web page, but I can't do any searches without an error coming up.
