My Dell E510 PC Desktop Does not turn on, the front light is green, but isn't blinking and a 3 and 4 show up. It also peeps a couple of times, but does not boot up
Computers & Internet - Dell - Dimension - Dimension E510 PC Desktop
Manual is here: http://support.dell.com/support/edocs/systems/dimE510/index.htm Look under Diagnostic Lights. 3/4 is a memory issue. Unplug your PC and open it up. If you have more than one memory stick, remove 1 and then try rebooting the computer. If it still fails, try the other stick instead. You may need to replace both sticks or even just reseat them both. Good luck!
