HERE is a link directly from Dell to what the diagnostic lights mean and possible solutions. Looks like it may be a memory issue but further troubleshooting will tell. Dell is usually pretty good about support even if you PC is out of warranty. At the very least they can help you diagnose the problem.

Power light amber with code 3 and 4


Hi,
Looks like Memory Issue,
Memory modules are detected, but a memory power failure has occurred.
You can try as follows :
  • If two or more memory modules are installed, remove the modules, then reinstall one module and restart the computer. If the computer starts normally, continue to install additional memory modules (one at a time) until you have identified a faulty module or reinstalled all modules without error. If only one memory module is installed, try moving it to a different DIMM connector and restart the computer.
  • If available, install verified working memory of the same type into your computer.
Let me know
Thanks

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.

The lights you see flashing are Diagnostic Lights. These tell you of a possible area to look into for the problem.

Lights 3, and 4 flashing green, mean a possible Ram Memory problem.

I would like you to view the free Owners Manual from Dell Support, in the event that you do not have one.

http://support.dell.com/support/edocs/systems/dime521/en/index.htm

This PDF document can also be saved to your computer, thereby allowing you to copy it to a CD disk. If you are not aware of how to do this, and wish to, simply state so in a Comment.

(After you burn this PDF file to disk, you can remove it from your computer, freeing up more space on your harddrive)

Where it states Owners Manual, left-click on View to the right.

You may also be interested in viewing, (And copying), the Service Manual.

What I would suggest to start.

1) Computer off, unplug your computer from power.
Working on a table, open the computer case.
TOUCH the metal frame of the open computer case.
(Not shouting)

This action will relieve your body of Static electricity.
Your body carries Static. Static will fry out (Short Circuit) computer hardware components.
(Should you get up in the middle of working on your computer, and leave, upon your return Touch the metal frame again)

Remove all ram memory modules. (Ram Module = Ram 'stick')
Use a pencil eraser, and clean the gold plated contact pins on the bottom of the ram module.

This is a photo of a basic ram module,

http://en.wikipedia.org/wiki/File:Generic_DDR_Memory_%28Xytram%29.jpg

Here, you can see the gold plated contact pins I have referred to.

(Ram Memory used for the Dimension E521 Desktop PC, is DDR2 Sdram.
DDR2 Sdram has 240 contact pins. 120 on each side.

The photo is of DDR Sdram.
184 contact pins, 92 on each side)

If possible, it is preferred to hold the ram memory module by the body of the module, and refrain from touching the contact pins. The body of the ram memory module is covered by a see-through plastic.

Start at the top of each contact pin, and work down, using the eraser.
Remove the eraser dust with air, and reinstall.

If you have two ram modules, try inserting one at a time.
The ram slot closest to the Processor, is Ram Slot 1. (May be marked as DIMM 1 on the motherboard)

Ram memory should be installed in ram slot 1 first.
The Processor reads ram memory installed in ram slot 1 first.

In the Service Manual if you click on - Technical Overview in the main menu, then click on - System Board Components, you'll see where the Processor
is located, (2 - processor socket), and where the ram memory slots are, (3 - memory module connectors)

Removing and Installing Parts, located in the main menu also, will show, and tell you how to open the computer case, and how to remove, and install ram memory modules.

(Removing the computer cover. Memory)

Should you need more in-depth guidance of how to do the above, please state so in a Comment.
Should this not fix your problem, please state so in a Comment.

My Dell Optiplex GX520 will not boot. There is no video output and the 3 and 4 diagnostic lights remain on.


If 1 & 2 are off ... then you have problems.

Memory modules are detected, but a memory failure has occurred.
  • If you have one memory module installed, reinstall it and restart the computer. (see Memory for instructions on how to remove and install memory modules.)
  • If you have two or more memory modules installed, remove the modules, reinstall one module, and then restart the computer. If the computer starts normally, reinstall an additional module. Continue until you have identified a faulty module or reinstalled all modules without error.
  • If available, install properly working memory of the same type into your computer.
  • If the problem persists, contact Dell (see Contacting Dell).

According to Dell's notes:
Memory modules are detected, but a memory failure has occurred.

Their remedies are:
  • If you have one memory module installed, reinstall it and restart the computer. (see Memory for instructions on how to remove and install memory modules.)

INSTALLED 1 GB MEM STICK AND NOW COMPUTER WON'T START?


The memory module you installed may not be the correct type. Try removing it and if the computer starts fine after that, the memory is either wrong for your computer, or it is a bad module.

Go to www.crucial.com and run their memory scan tool. It will tell you the exact type of memory your computer uses. Compare that information to the sticker on your memory module.

When I start up my computer, the screen stays black. However, the light flashes indicating that it is working, and the computer makes the starting sound.


Test your notebook with an external monitor attached to the VGA port on the side of your notebook. If both internal and external monitors have no image, this problem is not related to the notebook screen.

It could be memory related problem. Try reconnecting the memory module. If you have two modules installed, remove them one by one and test the laptop with each module separately. It’s possible that one of the memory modules is bad and your notebook will start as soon as you remove bad RAM.

When i turn my computer on, it gives two long beeps, the machine is on but the screen stays blank, as though its on sleep, what do i do?


Two long beeps is the code for memory trouble. Try removing the memory modules from their sockets. Make sure the sockets are free of dust (computers can get pretty dirty inside), using compressed air (available canned from office supply places, Wal-Mart, etc.) to blow them out if needed. Make sure the contacts on the modules are clean. You can use a pencil eraser with light pressure to clean them off. Reseat the modules firmly in their sockets. Then try restarting the computer.

If the trouble continues and you have more than one memory module in the system, try replacing them one at a time and restarting the computer to try to determine which one is causing the trouble.

If the trouble still won't go away, see if you can borrow a known good memory module from someone and try that. You might have a failed system board or multiple bad memory modules. (It can happen, and can drive you nuts when you try the "one-at-a-time" trick. I've been there!)

Hope this helps!
