An old Dell Optiplex gx260 just won't turn on

My old Dell Optiplex gx260 just won't turn on. The little yellow light on the motherboard does light up when the computer is plugged in, but when I close it's case and press the button to turn it on, nothing happens. And I really mean - nothing. Can you please tell me possible causes.

If the power LED is flashing amber, there may be an issue with the power supply, if it is solid amber then the motherboard itself (or if it has an expansion card in a slot, maybe the card)

Dell Optiplex Power-on Problem


An Amber or Yellow power button means that the power supply is receiving power from the source but is unable to properly distribute it to the components. This can be caused by a defective power supply or a defective motherboard. Just to make sure that nothing else is causing the problem, remove any PCI cards like modem, video card, sound card, etc...
Look at the USB ports to see if any are damaged.

Orange power switch light Dell Gx260


Gx260-Gx280 have a known issue with the motherboard capaciators. Take a look at the capaciators on the motherboard and check if any look like they have bludges at the top particularly around the memory banks. If any of them look like this the motherboard most likely needs to be replaced.

Dell PC Desktop Optiplex GX260 Doesn't boot


Open up the case and remove any add in cards and memory modules. Try to start up by adding these back one at a time until the unit stops booting normally. The light combination is not one recognised in the user manual so I am guessing you have a non-descript fault with one of your components. Be careful when you open the case as to not disturb the ribbon to the motherboard which controls the power, I have had a very long experience trying to get one of these reconnected!

hope this helps.
