The computer shuts down completely. 3 Remove the memory module, following the instructions in "Removing a memory module" on page 56. 4 Reinstall the memory module, following the instructions in "Installing a memory module" on page 51, and making sure the module is seated properly. 5 Check for the error again. 6 If the error recurs, remove the memory module entirely and check for the error again.
