Cant boot up Computer- Memory address line failure

You need to insert the CD/DVD that came with your computer and boot from that.

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: 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: The orientation of the diagnostic lights may vary depending on the system type. The diagnostic lights can appear either vertical or horizontal.

Light Pattern

Problem Description

Suggested Resolution


The computer is in a normal "off" condition, or a possible pre-BIOS failure has occurred.
The diagnostic lights are not lit after the computer successfully boots to the operating system.
Plug the computer into a working electrical outlet and press the power button.


A possible BIOS failure has occurred; the computer is in the recovery mode.
Run the BIOS Recovery utility, wait for recovery completion, and then restart the computer.


A possible processor failure has occurred.
Reinstall the processor and restart the computer.


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.

A possible graphics card failure has occurred.

• If the computer has a graphics card, remove the card, reinstall it, and then restart the computer.
• If the problem still exists, install a graphics card that you know works and restart the computer.
• If the problem persists or the computer has integrated graphics, contact Dell.

A possible floppy or hard drive failure has occurred.
Reseat all power and data cables and restart the computer.


A possible USB failure has occurred.
Reinstall all USB devices, check cable connections, and then restart the computer.


No memory modules are detected.

• 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.

Memory modules are detected, but a memory configuration or compatibility error exists.

• Ensure that no special memory module/memory connector placement requirements exist.
• Verify that the memory modules that you are installing are compatible with your computer.
• If the problem persists, contact Dell.

An other failure has occurred.
This pattern also displays during System Setup and may not indicate a problem.

• Ensure that the cables are properly connected to the system board from the hard drive, CD drive, and DVD drive.
• Check the computer message that appears on your monitor screen.
• If the problem persists, contact Dell.

After POST is complete, all four diagnostic lights turn green briefly before turning off to indicate normal operating condition.
None.

A beeping computer can generally mean some bad/corrupt memory and the PC will not boot until it is remedied. You will need to power off the PC, ensuring you unplug the power cable each time. Take out a piece of memory, at a time, leaving the other memory, still in the PC, depending upon how the memory is read based upon the motherboard reading the dim (memory) slots, power back up and re-try. It is basically a process of elimination, until you find the bad memory. Also, depending upon your Dell model, there maybe some diagnostic lights at the rear of the PC to also indicate where the issue may lie, albeit, memory, motherboard, graphics, etc.

Are you Sure that the computer model is Dell Optiplex GX260? Because looking at the manual diagnostic lights are found at the back. and the fault can be determine If the ABCD lights are yellow or green. But None the less 2/3 Depicts a hard drive problem while 3/4 depicts a memory issue.

Hard drive Issue:

1. Disconnect all non essential cables at the back of the computer. Leave only the mouse, monitor and keyboard. See if it boots up normally
2. If it boot up fine. try plugging one peripheral at a time until you find which peripheral causes the computer not to POST (Power on Self Test)
3. If you still getting problems, Follow these steps
4. To access the BIOS you must tap F2 or delete key upon turning the computer on
5. Try to look for the Hard drive if it is detected by BIOS if not got to step 9
6. Look for Boot Sequence or anything that is associated Boot
7. The Order boot of must be 1st: DVD Drive, 2nd: Hard drive, 3rd: Network etc.
8. Save the changes and Restart
9. If you still get the same message I suggest that you take out the hard drive and put it back in until it is detected in BIOS
10. If Step 9 did not work I think you need to replace the Hard drive

Memory Issue:

1. Open the chassis of the computer
2. Try taking out all memory modules
3. Rub the metal contacts of all memory with a pencil eraser
4. If more than one memory. Put one memory first and turn the computer on. If it turned on add another memory and turn the computer on. Repeat these steps until you determine which memory is faulty or all memory module contacts needs cleaning

This is called a beep code. It is used for troubleshooting when you are unable to boot your computer. Here is a listing of the Dell beep codes, depending on the sequence of beeps that you are hearing, you will find the problem listed here. How many beeps are you getting and what model of Dell do you have?

if you have 2 memory's try to remove one check sys then remove 1st and try second try them in different slots. Try to disconnect HDD and then try too boot diag CD

This is clearly a problem with the memory. You can try two things:

1) Remove and reseat the memory sticks (with the unit unplugged)
2) Swap the boards around. Windows is not very tolerant of errors in the lower portion of memory. Swapping around the boards will change the relationship of physical memory addresses to virtual addresses. At the very least, the memory swap may help to determine which memory stick is defective.

Please keep us posted.

If you can not boot into windows yyou can try to do an inline repair of windows

Please refer to this web address http://support.microsoft.com/kb/315341/ to get a better understanding for what is an inline repair.
