Hiya I might be wrong here but I didn't see you renew the chrome-profile on your computer.
Just like in Firefox a defective profile can render your browser useless. And if you re install chrome, chances are the same profile is used for that too.
It's quite simple and usually clears things up:
#1 close Chrome (you might even check in Taskmanager if it's really closed
#2 go to C:\Users\<Username>\AppData\Local\Google\Chrome\User Data\
There you'll find the folder Default
rename it to something like Default.Backup or so
#3 Start Chrome a new folder Default will be created and thus your profile is renewed.
#4 It's generally not recommended because some things there were corrupted, but if everything works as expected you may carefully put items from the old profile back into the new one (like bookmarks etc.)
Of course chrome need to be closed again at that time
