Introduction
The Alienware X51 R1, R2, and R3 shut down randomly when a computer's RAM starts to fail. This can be problematic with wear but is easy to fix with basic tooling. Before beginning the repair, a user must have a Phillips-head screwdriver and two eight-gigabyte RAM memory cards for a total of sixteen gigabytes.
NOTE: use an anti-static wrist strap when working to prevent circuitry damage.
