roubleshooting System Memory
A computer memory problem can be a faulty single in-
line memory module (SIMM), an improperly configured
or faulty memory expansion card (if one is installed), or a
faulty system board. If a random-access memory (RAM)
error message appears, the computer 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 momentarily and then remain on;
otherwise, it should turn off. Abnormal operation of these
indicators can result from a defective SIMM in socket A.
Follow these steps to troubleshoot system memory:
1.
Turn on the system, including any attached
peripherals.
Does an error message appear indicating invalid sys-
tem configuration information after the memory
count completes?
Yes. Go to step 2.
No. Go to step 8.
2.
Enter the System Setup program to check the
Total Memory or System Memory category.
Does the amount of memory installed match the
Total Memory or System Memory setting?
Yes. Go to step 8.
No. Go to step 3.
