This means totally dead, only clicking sound from internal buzzer and blinking power button led.

Dell optiplex sx280 fans to loud! How do I turn them down?

1) Tell them to be quiet. The kids are sleeping.

2) Promise them a nice quiet vacation in the Bahamas, if they will just be quiet for now.

3) In a firm voice tell them that they CAN be replaced.

1) Suggest you replace the Thermal Paste on the Processor.
It has dried out.

2) Also clean the inside of the computer out. Suggest it is dirty inside.

(Wuz trying to just be funny................Alan?....................Alan?)

The top of a Processor (CPU), and the bottom of the fined Heatsink that sits on it; are not perfectly smooth.
A magnified view would detail, 'Ridges, Valleys, and Pitholes'.

When the two parts are mated together, Air Pockets are created.

Air is an Insulator in this case, Not a Conductor.
Thermal Paste fills the above imperfections, and is an Excellent conductor of heat.

Thermal Paste dries up over time. Looses it's thermal conductivity properties.

It's cheap in cost.

Can guide you step by step in replacing the Thermal Paste, and also cleaning out the inside of the computer.

How do I make my Dell Optiplex SX280 wireless?

Just the wireless router I'm pretty sure it comes with all you need. Ask the store rep about this when you buy it, they will know which one you are buying, and what goes with that is not included. It should have a cd which you insert, and then follow directions given.
