Question about Dell C521 DimensionTM PC Desktop
I was using my Dell C521 and and left it on to go get something out of town. When I came back the computer was on but nothing on screen, so I thought it was on sleep mode so I press the power nob to get it out of the sleep state and that was it. When I turn it on the front panel under where the front USB and sound / mic ports are, light up indicator lights 1, 2, and 3. I don't know what o do to get the computer to even show the POST on my monitor. Any help will be gratefully appreciated.

It appears that your video circuit has a problem, not the monitor but the graphics card or on board graphics controller.
