Computer Memory Problems
During POST, the computer checks the computer's memory, determines the
amount of installed memory, and then writes to and reads from the number
of available bytes to ensure proper operation.
Basic Checks:
• If an insufficient memory message appears, save and close any open
files and exit any open application programs not in use.
• Consider installing additional computer memory.
• Run the System Memory test in the Dell Diagnostics.
• Reseat the memory modules.
• Restart the computer.
If the problem still exists after you complete the basic checks, fill out the
Diagnostic Checklist as you perform the following steps.
CAUTION: Before you perform this procedure, see " Safety
Instructions ."
