In my case it turned out to be a weak power supply. It would work sometimes and not others. If stone cold, it would not boot. If I unplugged 1 thing, like the hard drive or the CD Roms, it would boot. Tested the old power suppy and it seemed to pass. But once I connected a new power supply, the computer has worked fine ever since.

Flashing power LED light means you may have shorted (Emitter to Collector) out transistors (c5707) or bad fuse (fuse has high resistance) PF751. Those are what you need to check. see pictures here: http://s807.photobucket.com/albums/yy352/budm/Dell%20E173FPb/

Monitor problem


The power light is flashing green can indicate start/restart of the power supply due to shorts circuits or failing power supply due to bad caps, look for bad caps with bulging top first, see example of failed monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums

Monitor wont turn on, just green flashing light.


double check that all yor connections are tight. Open your PC case (unplug it) and ensure that all your fans are clean. It appears that your problem is due to loose cable connections, but this may be a good time to do some computer spring cleaning.
