    Sounds like a hard drive issue at first glance. Can you boot up from a CD and see if you can see the HDD? Could be that your hard drive either needs a format or a new hdd installed in the systems. Try it and report back your findings. Good luck God Bless -Carlos:

Sounds like classic motherboard failure for this model.
Did you buy these secondhand or EBay or in some fire sale...

This model has a well-known history of motherboard failure.
The capacitors used by Dell (purchased from electronics component vendors) on the motherboard, usually surrounding the CPU socket fail.

You can generally tell by looking at then. If the tops are bulged, discolored or leaking, then you have your answer. (There was for a time comments that the ones with an "X" on the tops were prone to fail). The capacitors look like little soda cans, colored metal cylinders, with metallic round tops.

You can solve it by replacing the motherboards, which isn't hard to do, but tedious...and a little pricey. There are also lots of people on google and EBay who will replace all the capacitors for a fee, again tedious but not terribly hard to do.

It would certainly be unusual to expect 4 machines to all fail at once, but maybe some additional info about the history, or source of your units might help.

Dell Studio xps 8100: Motherboard changed, when booting up I get to the f2/f12 screen with have a progress bar and computer turns off?


So picture guy, LOL

Most all boards have two power plugs from PSU, (power supply unit)
a 20 or 24pin and a 4 or 8pin.

The rest from PSU are for hardware, except if you have any video cards in pci-e slots, but they are not truly part of the motherboard they are addon.

Then from the case you have power button, reset, pled,hdled.

Sata ports on mobo, cpu fan, addon fans, DVD rom.

Front panel audio.

So now you have taken one memory stick and entered the BIOS, then tried each one.

You need to check each stick.


Now you put in your hdd erase disk, boot from it and you're going to erase your hdd so it's all clean for a fresh install.

Now you throw in the windows disk and you boot from it to install windows.

Right !!!

How to fix your dead Dell Optiplex-SX280


If the Dell Optiplex-SX280 doesn't boot anymore.
This means totally dead, only clicking sound from internal buzzer and blinking power button led.
Look to the "big" Capacitors top cap.
If they are pushed above you have to replace them.
Fixed, see below link

IN dell optiplex sx280 model system we are using in this amber power led blinking continuly yellow color because of this not able to boot the system. kindly give the solution for the same


Hi there!

A blinking amber/orange light on the power button of your Dell Optiplex means a hardware failure. If you know how to strip down your computer to basic component, then I suggest you turn on with only the motherboard, processor, memory and PSU. If you are not familiar with this, I suggest you bring the computer to a qualified technician.

Hope this helps

Yellow blinking power button


A customer of mine has several of these that have the same problem. I found a comment on a Dell forum indicating that one of the capacitors on the mainboard will be either swollen or leaking. Replace the capacitor and it should be OK. I do not have the proper equipment for soldering on a mainboard so I have not done this. However, I did a google search on "Dell SX280 mainboard purchase" and I found a guy on ebay selling the repaired boards for $100.
