Laptop built in keyboard is not working

So I'm unsure whether this is a hardware or software issue.
I didn't use my laptop for a few days and when I turned it on most buttons on the keyboard either type a different letter, presses a utility key or does nothing at all.
A few examples my a button types the time and date, my Fn key presses F2 and v presses delete.
I have searched for a solution and found the following:
change the language
set keyboard layout to qwerty
remove the keyboard driver
press num lock
restart my computer
none of these worked and I can't find any other solutions.
any help would be appreciated.
 
Find the model number of your laptop underneath it, bring it back here.
Specify which windows OS is currently installed on it.
 
Its an Acer aspire E5-411 running windows 10
another thing I tried is accessing the bios but when started it from power down I never got the text saying what button to press. also repeatedly pressing f1, f2 and delete didn't do anything
EDIT: I checked for updates so its the latest version
