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 for technical assistance.
No. Go to step 3.
3. Turn off the computer and peripherals, disconnect them from their electrical outlets, wait at least 5 seconds, and then remove the computer cover.
4. Rotate the power supply away from the system board.
5. Replace the memory module(s).
6. Replace the computer cover, reconnect the computer and peripherals to their electrical outlets, and turn them on.
Does the RAM count displayed correctly match the actual amount of memory installed in the computer?
Yes. The memory module(s) were defective. The problem is resolved.
No. Contact Dell for technical assistance.
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.
If the problem still exists after you complete the basic checks, fill out the Diagnostics Checklist as you perform the following steps.
1. Run the System Board Devices and Processor Cache test groups in the Dell Diagnostics.
Did any of the diagnostics tests fail?
Yes. Contact Dell for technical assistance.
No. Go to step 2.
2. Turn off the computer and peripherals, disconnect them from their electrical outlets, and wait 10 to 20 seconds.
3. Lay the computer down on its right side.
