I have a HP Pavilion g7 1227 nr. I have changed the hard drive out and cleaned the fan because it was running hot. I have also replaced the keyboard once. I have updated to Windows 10 and for the most part everything works well except on start up the upper letter row does not work. This happens on start up and then will kick in after awhile.
I have deleted the keyboard in device manager and updated all drivers. Nothing seems to work. I am bewildered as to the issue.
