Below I've lined-up common Memory problem its cause and solution.
Problem 1:
System will not boot or does not function properly after installing additional memory modules.
Cause:
Memory module is not the correct type or speed grade for the system of the new memory or the new memory module is not seated properly.
Solution:
- Replace module with the correct industry-standard device for the computer.
- One some models, ECC and non-ECC momery modules cannot be mixed.
Problem 2:
Out of memory error.
Cause:
Memory configuration may not be set correctly. You have run out of memory to run the application.
Solution:
- Use the Device Manager to check memory configuration.
- Check the application documentation to determine the memory requirements
Problem 3:
Memory count during POST is wrong.
Cause:
The memory modules may not be installed correctly. Integrated graphics may use system memory.
Solution:
Check that the memory modules have been installed correctly and that proper modules are used. No action required.
Problem 4:
Insufficient memory error during operation.
Cause:
To many Terminate and Stay Resident programs (TSRs) are installed. You have run out of memory for the application.
Solution:
Delete any TSRs that you may not need. check the memory requirement for the application or add more memory to the computer.
Problem 5:
Power LED flashes Red five times, once every second, followed by a two second pause, and the computer beeps five times. (Beeps stop after fifth iteration but LEDs continue flashing.)
Cause:
Memory is installed incorrectly or is bad.
Solution:
- Re-seat DIMMs. Power on the system.
- Replace DIMMs one at a time to isolate the faulty module.
- Replace the memory (RAM).
- Replace the system board.
