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.

  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?

Six beeps at post and no joy with boot up

The exact meaning of the beeps for Dell depends on their... rhythm.

Six beeps might indicate a simple CMOS failure caused by a bad battery, which is easy to replace.

Boot problem with Dell Optiplex GX150

To reinstall Xp from the CD you need to press F2 and go into the BIOS then select the boot order configuration and make the CD the first boot device and the hard disk the second boot device.
After installing XP, if you wish you can go back into the BIOS and change the boot order to boot from the hard disk first.

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.
