Troubleshooting System Memory
A system memory problem can be a faulty dual in-line memory module (DIMM) or a
faulty system board. If a random-access memory (RAM) error message appears, the
system probably has a memory problem.
When you turn on or reboot the system, the Caps Lock and Scroll Lock indicators on
the keyboard should flash momentarily and then turn off. If the Num Lock category in
the System Setup program is set to On, the Num Lock indicator should flash momen-
tarily and then remain on; otherwise, it should turn off. Abnormal operation of these
indicators can result from a defective DIMM in socket DIMM_A.
