How Do You Test Memory For Errors?
Computer memory or Random Access Memory (RAM) is a data storage interface between the processor (CPU) and all running applications including operating system (OS). RAM is among the most important hardware components that determine the computer performance. Defective RAM often leads to system crashes or Windows OS failure (blue screens). Memory testing is a critical step in computer troubleshooting. Memtest86 is one of the best freely accessible programs that comprehensively tests the every physical address of RAM and reports errors (if any). Insert the bootable Memtest86 CD in the CD/DVD drive and reboot the computer. When the computer starts to boot up, press the “Del” key to enter the system setup called BIOS. The “Del” key works for the majority of motherboards, but you may need to refer to your motherboard manual to find what key should be used. Navigate to the “Boot” BIOS menu and then to the first boot device. Press “Enter” and select “CD-ROM” from the list. Press “Enter” again.
