Ordered on line from manufacturer Asus Technology Services, 211 River Ridge Circle, Jefferson, Indiana 4713. Received a defective mother board and despite several returns for repair and or replacement continues to return the same unit and just recently sent a used and malfunctioning mother board stating the product is good. The unit crashes the computer and has a malfunctioning USB port despite the manufacturers quality control reviews.

Purchase of a new mother board locally resulted in perfect computer performance validating the defectiveness of the mother board purchased from Asus Technology.

Seeking a refund or replacement of a new guaranteed mother board. Situation has been ongoing for months.
