Not short of changing the keyboard itself - which you should request if the system is under warranty.

You might try going into the old control panel -ease of access- make the keyboard easier to use and see if  any of the boxes are checked there.  Uncheck them all under keyboard .Dont know if it is your problem but my keyboard certainly worked better after unchecking them.Also  check repeat rate under settings--devices--keyboard.. Hope this helps.Otherwise it does sound like a hardware problem.
