Create a boot CD or floppy to test your system's memory, but novices shouldn't expect much help. Memory Diagnostic's first interface is a simple two-button dialog box to create a startup disk or save a CD image. Whether you burn the CD or create the boot floppy, the second interface is the same. Boot your machine and Memory Diagnostic's DOS-like interface presents just the facts. The program tests your system memory six different ways, all involving storing select characters in specific patterns to your system memory. The program quickly reads back the memory to find flaws. An old-fashioned spinning cursor displays test progress. Memory Diagnostic explains each test and lists test memory locations. Other than that, you're notified if an error is found. The tests repeat until you press a key to halt the program. Novices would appreciate a bit more information about memory problems. System administrators and home repair techs will carry this freeware executable to quickly determine if problems are caused by faulty memory.
