Download the precompiled, latest Windows version (Memtest86 v3.2) or the ISO image from www.memtest86.com to create a bootable CD. Start your PC and go to the CMOS/BIOS setup by pressing the appropriate key (most likely [Delete] or [F2]) and change the boot priority to CD-ROM. Save the changes and exit the CMOS/BIOS setup. Your PC will boot Memtest86, a tool that is independent of the installed OS. The help bar, located at the bottom of the screen, guides you through the process of memory testing. All you have to do is press [C] to enter the main menu from which you can choose ‘Test Selection’. Advanced options such as Cache mode, ECC mode, Address range, etc. are also available from the main menu.
