Numbered lights flashing

[Kaorichan2009]

Im trying to diagnose a problem on my brother's computer and I need a little bit of help. He has a Dell Inspiron E521 and the lights 3 and 4 on the front are flashing in Green. Is it bad ram? X_X i hope its not the power supply

• 1. Reseat the memory modules to ensure that your computer is successfully communicating with the memory.
• 2. Restart the computer.
• 3. If the problem still exists, remove all the memory modules and install one memory module in memory module connector 4.
• 4. Restart the computer.

The following message appears: Alert! Operating in Debug Mode. Please Populate Memory in Pairs for Normal Operation.

• 5. Press <F1> to boot to the operating system.
• 6. Run the Dell Diagnostics.
• 7. If the memory module passes, shut down the computer, remove the memory module, and repeat the process with the remaining memory modules until a memory error occurs during start-up or diagnostic testing.

If the first memory module tested is defective, repeat the process with the remaining modules to ensure the remaining modules are not defective.

• 8. When the defective memory module is identified, contact Dell for a replacement.

NOTE: If necessary, the computer can operate in debug mode until new memory modules are installed.

My concern on this is that you say the lights are blinking, and the documentation indicates a solid light for the light code. I would suggest reviewing the URL noted above. If you have difficulty using Dell's memory diagnostic, we would suggest Memtest, per this tutorial... https://www.techspot.com/vb/topic62524.html

Dirty contacts or dust buildup?
I assume the former, as the later would normally cause heat to build gradually and then start causing errors.
