Motherboard will not include I/O Shield, Tested in original machine under load conditions before removal and visually inspected for defects. The key function is to provide power, data transfer, and user interface abilities with the computer. We test by checking CPU socket, RAM slots, and the overall board for damage, test the RAM slots and boot the board to BIOS, verify function of I/O ports and expansion slots, and inspect for bulging, damaged, or missing capacitors. All products have passed all tests prior to testing.
