hi JFHarrod,
correct me if i am wrong... after replacing the keyboard the symptoms remain although USB keyboard works fine. you did not reinstall Windows, correct?
surely looks hardware but could be other reasons as well. try running a live CD of another operating system like Linux (i.e. Knoppix or Ubuntu). this way, you will know if it is virus/malware related, hardware or corrupt Windows files.
