System 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:
l
If an insufficient memory message appears, save and close any open files and exit any open application programs not in use.
l
Consider installing additional system memory.
l
Run the
System Memory
test in the
Dell Diagnostics
.
l
Reseat the memory modules.
l
Restart the computer.
If the problem still exists after you complete the basic checks, fill out the
Diagnostics Checklist
as you perform the following steps.
1.
Reboot the computer.
Does the random access memory (RAM) count displayed correctly match the actual amount of memory installed in the computer?
Yes
. The computer needed to update the memory count. The problem is resolved.
No
. Go to
step 2
.
2.
Run the System Memory test group in the
Dell Diagnostics
.
Did any of the diagnostics tests fail?
Yes
.
Contact Dell

Microprocessor Problems
During POST, the computer checks the computer's microprocessor and determines its operational specifications. This information is stored in
system setup
.
Basic Checks:
l
Run the System Board Devices and Processor Cache test groups in the
Dell Diagnostics
.
l
Enter
system setup
and ensure that values for the microprocessor under the
CPU Information
option are accurate.
l
Reseat the microprocessor.
l
Reconnect the microprocessor cooling fan.
l
Restart the computer.
