I have a Dell Optiplex Gx 280 LGA 775 motherboard that I want to test and see if it workls. I try to power this board with a 400watt power supply to test it. I installed a 2.66Ghz Celeron CPU and I do not get any video, only an amber light. Any suggestions?

I would check the capacitors carefully and see if any of them are leaking or oozing. The 270s and 280s had a long, bad run of mobos with leaky caps (they were overfilled during manufacture). Dell ended up recalling them and replacing them with new boards with Rubycon caps, but now the recall is over, so I hope you are either lucky or good with a soldering iron...

I just go this motherboard and the seller told me that is worked. I power up the board with ram a 2.66Ghz Celeron D CPU, but I get no video. The fan does not get loud.

The CPU is compatible since the motherboard takes a socket LGA775 Celeron D and Pentium 4 up to 3.4

I plugged in a PCI express video card and used the on board video, Nothing! I came down to the conclusion, the board is bad and is trash. I will order another board and I will keep you posted. Thank you for all your help!

I found another one on Ebay and it worked just fine. Like you said capacitor issues.
