Re: Dell Dimension 5100 Won't start up
First disconnecting the power cord and re-seat all connections (Keyboard, Mouse espercially). Connect up the power cord and try powering the PC.
To help you troubleshoot a problem, Dell Dimension 5100 has four diagnostic lights labeled "1," "2," "3," and "4" on the front panel. When the computer starts normally, the lights flash. After the computer starts, all four lights display solid green. If the computer malfunctions, the color and sequence of the lights identify the problem.

The Memory modules Make sure that they are pushed in securely in there slots and video card is Pushed in and tight, and any other extras you may have plugged into it, After you do all that put everything back and try to reboot see if that get you up and going.
