I have a Dell Dimension 2400 Home Edition. The on light doesn't show the computer is turned on but I can hear it humming.  I've tried turning it off and on several times and it just won't start up.   I had unplugged it a couple nights ago when the electric went out because it isn't plugged into a surge protector.  This morning when I plugged it back in, it just wouldn't work.  The speakers show they are turned on and the monitor light is amber and the computer is humming, so I know it's getting power.  Where do I go from here?

Howszit? and Welcome to GtoG...

 

Sorry to hear that your Dell doesn't want to start at all.  I've had experience with quite a few Optiplex models and usually the power light glows amber instead of green when the PSU goes bad. According to the Dell website if it is not making any beeping sounds they suggest several steps...  (see issue 2 on this web page ...  http://www.dell.com/...19/SLN127731/en

 

In rare cases, I've had power cables that have gotten so aligned that I had to spread the male connections a bit to restore a power connection.  Make sure where the hum is coming from, (might be your speakers?)

 

Cheers and hope this helps...

Depending on the speakers, most get their power from 110vac.

The monitor light being amber means it is getting power. It will turn green when receiving its info from the computer.

The hum could be from the speakers.

 

Make sure the power plug to the case is securely plugged in.

You could have a bad psu (power supply unit) inside the case or a bad board.

 

The next step is to take the side off the case and look at the board. There should be a green or blue (usually) somewhere on the board that indiactes it has some power.
