Dell xps 400 will not boot.

This question is not answered

I purcachased a dell xps 400 a few years ago, and now it will not boot. Although, when the PSU is plugged in, the mobo light is on. I've tried unplugging it for 12 hours then plugging it back in, only to hear the computer breifly start up (fans and harddrive) only to quickly shutdown. I then tried hitting the power button, but it would not boot. I've also tried a different power outlet and cable, as well as unplugging everything. I also checked the cables inside the computer and made sure they were tight.

Thanks for hearing me out Smile

  • what is the color and condition of the power button light. how about your diagnostic lights?

    You said you unplugged everything does that mean you pulled out all the ram sticks, pulled out all the cards and disconnected the power connectors going to all the drives?

    If not try that with everything out if you power on the system and the fans spin up then the motherboard is the most likely cause.

  • I'll try unplugging some other stuff later then, as far as my power light..... it does not go on. Completely dark.

    And these diagnotsic lights, what exactly are they? I only see one led inside the mobo that is green

     

    EDIT I think I found the problem, something in plugged in....it's a narrow space, so it'll probably take some effort to get it back in. I'll post bak with results.

  • See HERE for diagnostic lights.
