That is a Memory or RAM failure. Did you recently install additional RAM, or do any work inside the laptop? Try a reset: If you get the same error, try this: If you continue to see that error, repeat steps 1 through 5 again. Then remove one RAM module and test the other RAM module alone in each of the RAM slots. Then test the other RAM module alone in each RAM slot. The goal is to see if one RAM module is bad or if one RAM slot is bad. Whenever touching components or working inside a computer, wear a grounded wrist strap, also called anti-static wrist strap, ESD wrist strap, or ground bracelet. It's a cheap and sensible precaution. Rest the laptop on an anti-static mat or at least a reasonable alternative such as corrugated cardboard. (Repeatedly touching a metal case part is not sufficient mitigation with modern components.)
