SOURCE: 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.

It turns itself off when there is something wrong with it. You can check the system events from the bios menu why it does that. When it doesn't boot at all check the abcd lights at the back.

blinking yellow light on the power button of a Dell system is a possible power supply issue. press the eject button on the dvd drive while the power button flashes yellow light. if the disc trays wont come out, you need to replace the power supply. hope it helps. good day.

How's the status light of your computer monitor? is it blinking amber? and the status light of your computer tower's power button? blinking amber as well or solid green or no light at all?
1. Disconnect all the connection at the back of your computer tower
2. Press the power button of the computer tower for 15 seconds
3. Reconnect the power button and the monitor cable at the back of your computer tower and turn on the computer (if it turned on that means that one of the device plugged at the back of your computer tower is faulty)
4. If still the same problem, open up your computer tower.
5. Reseat the video card, Reseat Hard drive, Reseat Memory, Reseat CPU, Reseat power cord coming from the CPU to your computer (doing all things one-by-one to pin-point the root cause of the issue)
If none of the troubleshooting steps fixed the problem, possible that the power supply is faulty and if the power supply is faulty sometimes it goes with the motherboard.
