    My dell optiplex gx620 does not start and it shows no. 3 and 4 lights illuminated on its front . what could be the problem.?


    One of your memory chips is bad.

    Maybe your memory is bad or the memory slot is bad.

    Remove the Power Cord, Open the Case and remove one of the memory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x on it with an ink pen. If it fails to boot then move the chip to the next memory slot and try rebooting. If it fails take the chip out and set it aside, then put the other chip in and try booting it in both slots. If it boots, just to verify that the chip set aside is bad, mark an x on it and put it into the open memory chip slot and try booting.

    Diagnostic Lights caution.gif CAUTION: Before you begin any of the procedures in this section, follow the safety instructions located in the Product Information Guide. To help you troubleshoot a problem, your computer has four lights labeled "1," "2," "3," and "4"on the front or back panel. The lights can be off or green. When the computer starts normally, the patterns or codes on the lights change as the boot process completes. When the computer starts normally, the patterns or codes on the lights change as the boot process completes. If the POST portion of system boot completes successfully, all four lights display solid green. If the computer malfunctions during the POST process, the pattern displayed on the LEDs may help identify where in the process the computer halted.
    note.gif NOTE: The orientation of the diagnostic lights may vary depending on the system type. The diagnostic lights can appear either vertical or horizontal.

    Numbers 3 and 4 are flashing green on the front of the computer


    Dell website says that it means that the PC has memory installed, but there is a problem with it. It's possible that you have more than one memory module and one has gone bad. If you know how, you could try removing one, restarting the PC to see if the error is eliminated. If not, put the removed one back in and remove a different one until the error goes away. You may have to buy a new memory module. Additional troubleshoot tips on the Dell website at this link: http://support.dell.com/support/edocs/systems/dimE521/en/SM_EN/adtshoot.htm#wp1056411

    This is a problem with your memory.

    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 system 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.gif CAUTION: Before you perform this procedure, see "Safety Information."
    1. Reboot the computer.
    Does the 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.
    1. 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.
    1. Turn off the computer and peripherals, disconnect them from their electrical outlets, wait at least 5 seconds, and then open the computer cover.

    2. Rotate the power supply away from the system board.

    3. Replace the memory module(s).

    4. Close 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.
