the cost of a new PC. I assume that the cost includes labor and it will result in a guarantee that the problem has been corrected.
Remember when they replacxe the mobo they still use all of the other hardware components that make up a system. . Twould seem that saves you quite a bit.
No deal without a written warranty!!!!!!
