    Also, please forgive, me I understood that holding down the on/off button was to be done with the power cord off, perhaps that is not true. Thank you.

Usually the 6 long beeps refer to keyboard problem. This is an idea but in case your Dell uses the Optiplex bios this maybe different. Try the keyboard and post me back. Also take a look at the 4 leds at the connectors' side of the motherboad. What is their state, green or orange?

In case of a problem or clarification, don't hesitate to post me a reply.
If you are satisfied, accept my solution.

Thanks and regards

Remove and reseat all expansion cards and memory modules. Clean the cards/memory contacts with pencil eraser and clean the mainboard with air blower before re-inserting expansion cards and memory module. Insert memory module and video card (if external) then turn on the computer. If the computer turns on properly, re-insert all other expansion cards.

    There should be four (4) LED (small lights), which ones are on and what are the colors? Those are diagnostic lights and should tells us something.

Dell optiplex gx 280 beeps 6 times when turnd on and nothing happens


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.

Reseat all DIMMs and restart the system to retest.

I had 1 long beep, 3 faster beeps, then 2 beeps *I think*, and also my fan was going crazy fast - like someone else said "a vacuum cleaner"...
Well, I reseated the memory and problem was gone - it did seem like the memory was kind of "loose" - perhaps from shipping (bought this used).
The link to Dell's website was good for the beeps AND the "ABCD" codes reading on the back. Thanks very much! God Bless.

the problem description is
Ithr
Smm mode is initializing the thermal probes.

problably the system is running at high temperature because of improper fan speed, so try to clear the nvram if its not working flash the bios if still the issue persists, replace the heatsink assembly and the motherbord.

Dell gx 150


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.
