When troubleshooting memory issues, what should be the first step if a new computer does not boot?

When troubleshooting memory issues, the most logical first step is to verify memory seating and compatibility. This action is crucial because if the system fails to boot, improperly seated memory modules are a common cause of the issue. Memory must be securely fitted into the motherboard slots, and compatibility with the motherboard, in terms of type and speed, is also necessary for proper functioning. If the memory isn’t installed correctly, the computer may not complete the POST (Power-On Self-Test) process, resulting in a failure to boot.

Checking the display connections or ensuring the computer is plugged into a power source, while important, do not directly address potential memory hardware problems, which are often the root cause of boot failures. Likewise, reinstalling the operating system is more of a software-related solution that comes into play after hardware issues have been ruled out. Thus, confirming that the memory is properly seated and compatible is the most effective initial troubleshooting step when addressing boot failure in a new computer.
