The ram is either bad or unseated. Reme it all and reseat it. If that doesn't work, boot after adding each stick to find which stick or slot is bad.

I have dell optiplex gx 150 beeps 6 times and a and b led is amber and c and d led is green


the 6 beep codes will be in a specific timing i.e. two beeps, a space 2 more beeps, and another space and 2 more beeps.

Looks like it may be a memory problem according to the lights.

My dell dimension 2400 beeps morse code like and won't load


you have to follow the beeps very well to understand wat is the problem, each type of beep gives you sign for problem. so check if its one beep, two, or three, short or long, this makes very easy to you to define the problem.
Try to take out that parallel port if your pc works fine, this means this connector was not compitable to your board.

Best regards

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.

Chuck,
The 6 beeps are an error code. You should note a pattern such as 3 beeps, short pause, 1 beep, short pause, 2 beeps. Also, you may have a set of 4 error indicators on the back of the unit that will show a pattern of green and yellow lights. In any case, you will want to try to run the Dell diagnostics. Let us know the beep pattern and the light pattern and we should be able to give you some more specific information.
