I think that some more information is needed here.
Firstly, please confirm that you're using a Windows PC or, if not, tell us what you're actually using. (It's not unknown for us to go round in circles providing answers which only apply to Windows when, say, the questioner is actually using an Android phone).
Next, which browser are you using, please? (Internet Explorer? Edge? Chrome? Firefox? SeaMonkey? Safari? Opera? Avant? Vivaldi? Something else?).
Then, when you click on this link, does the Google search page open as usual?
https://www.google.co.uk/
If so, can you search from that page? (If not, what happens when you try?)
