Motherboard Analyzer Diagnostic Card Tester is a tool used to test the health of a computer motherboard. It does this by displaying the POST (Power-On Self-Test) code generated by the motherboard during the boot process. These codes can be used to identify motherboard problems, such as faulty memory modules, a bad CPU, or a problem with the BIOS.
Built in 4 digit led display on the card allows easy view inside computer cases
