ok so i was with my sister in the room. i was playing my xbox and she was on the computer. she was doin something i didnt want her to do on the computer...so i get pissed after telling her to stop like 20 times...and i go and take out the plug (that one plug that everything is connected to) Everything, including my printer, scanner, speakers, and monitor can be TURNED ON. While my computer doesn't want to turn on. Help?

u did a bad job???

What?

sorry, I was talking to Dell while i typed that, I ment that you did a bad job connecting the wires, Check the plugs and check where the plugs go.

i only unplugged on plug, and put it back.

 

 

 

 

 

 

 

everything but the computer itself will turn on

Try holding the front power button for ~10 seconds. If the computer doesn't turn on, look on the back for a toggle switch on the power supply. Flip it off and wait 10 to 20 seconds. Switch it back to the original position and try to turn the computer back on.

 

 

 

 

 

 

 

Some power supplies and motherboards have to have power completely shut off again after a sudden power failure to reset them, basically telling them it's "safe" to turn back on and that it isn't just a flicker of power. My older AMD tower does this. :P

 

 

 

 

 

 

 

If the above doesn't work, you may have damaged some hardware and would have to go digging deeper into the parts. :?

i've discovered a green flashing light in the back. It flashed slow if i switch a switch next to it, and goes faster if i switch the switch to the other side

That switch wouldn't be the voltage control, would it? You probably shouldn't be messing with that.
