I powered my dimension 3000 off before going on vacation for a week and after returning home I get nothing when pressing the power button. Any suggestions to get it running again? After taking the cover off there is one little green light on the motherboard that is burning when the power cord is plugged in. Other than that I get nothing.
Try unplugging from the wall. Remove ALL Cables. Hold the power on button until the light inside goes out.
Then ONLY Hook up the power cord and try to turn on. Then what happens?
I decided to try another power supply and that fixed the problem and when I put the one I thought was bad back in the other pc it still worked so ???? as to what was wrong. All wires were on good as I had trouble disconnecting them with my big fingers.
