Before You Begin

Back up your important data before any hardware changes. While the risk of data loss is low during RAM or SSD installation, a backup protects against the unexpected. You’ll need a small Phillips-head screwdriver and preferably an anti-static wrist strap.

If Something Goes Wrong

If your system doesn’t boot after the upgrade, remove the new component and reseat it carefully — incomplete seating is the most common cause of post-upgrade boot failures. If the issue persists, try one module at a time to identify a faulty unit. Check your BIOS settings, as some systems require manual configuration after hardware changes.
