It's most likely hardware problem.

Look at this board. You can see dirty keyboard contacts. To locate problem you can heat calc a little (by hair dryer, flowing to shoebox, where calc is placed or directly to calc back). The problem may be temporary eliminated, but I'm afraid, that you must disassemble this machine for keyboard prophylactic works.
