Im using windows 10, and these steps should work.
Lets focus on the first part.
Click the start button at the bottom left of your screen. In the text box type in these words
uninstall a program
Then, click on change or remove a program ( if you can get this far, t he rest should be easy!)
Find google chrome in that list. Click it and then click uninstall.
Make sure to check the box that says " delete browsing data"
Once uninstalled, restart the computer. And then download and install a fresh copy of google chrome from here.
Once installed, chrome should be working again.
If you get stuck or encounter any issues, let me know!
I strive to provide great service, and greatly appreciate a rating of excellent ( 5 stars ) selected and submitted below this answer or at the top right of the screen. I always answer follow up questions.
