You could put GFCI outlets, you would only need one at the beginning of the circuit and all the outlets connected to the load side of the GFCI will be protected, you should also place the "No Equipment Ground" label on the outlets that come after the GFCI.

Computer type equipment should have a ground. Like lcd tvs, etc. But yes, you can install gfcis to use three prongs.

Thanks for the response......This is an old cinder block house so all outlets run from a j-box in the attic down wall seperatly,can I put in some type of gfci breaker and then just change outlets with regular 15a?

Cinder blocks huh? Is the wiring in conduit?
