Having problems with your Dell OptiPlex SX280 PC Desktop ?
Dell dimension 4700 blinking yellow light
\015 My computer will not come on at all, I only get a blinking yellow light when I try to turn it on. my monitor reads no signal.\015
You clearly have an SMPS(power supply issue). Not 3 days ago I worked on my dad's PC that had the same problem. I found that the board had some leaky caps, and the circuit board inside it partially burnt. I could get it working by replacing the caps, but dont know how long it will last(I'll be getting a new PC soon anyway). Its advicable you replace the power supply. Should cost you around 30-50$ at MOST!
Are you getting any beep signals? You could have a massive motherboard failure or you could be having something a little easier to fix...like a memory failure...do a little research on beep codes on google if you are getting beeps from the motherboard...Also, try opening your machine and pulling out the memory sticks and trying them one at a time...if the machine works with one and not the other (for example) then you may need to simply replace that bad stick of memory...
