Error code 134, display turn on manually them off byitself

I have a Dell precision T-3400. It wouldn't turn on, had amber flashing power light, changed the power supply same thing. Found video card capacitor blown, changed the video card, got green light and error code 134. The monitor stays with amber light even after I turn computer on stays amber unless i turn it on...then green for a few seconds says entering power save then back to amber light again. That' where I am at. I disconnected all the ram cards, then both hard drives, the same results. Any ideas???

  1. From Dell:

    A possible systemboard resource and/or hardware failure has occurred.

    • Perform the procedures in "Restoring Your Operating System" in your User's Guide.
    • If the problem persists, contact Dell (see "Contacting Dell" in your User's Guide).


    Try starting with a bare minimum of hardware installed.
    Only your OS disk, only 1 ram module, etc

    If this fail, take out the ram module and try with a different one.

    If all ram modules fails, then dry a different DIMM slot for the ram and re-test.

    If all fails it looks like for some odd reason it might be your motherboard that is faulty.

  3. Well I didn't know there were differences in video card connections and installed an avg card into the pci-e slot!...I wonder if that is one problem I didn't need! I have since removed that card, and now instead of an error code 134, now it is 234 with video card removed. Could I have damaged the mb connector?

  4. Ups.
    Got to ask. Have you ever build a computer before?

    If the power light is green and "234" shows its: USB subsystem configuration activity in progress or USB subsystem failure.
    If the power light is orange and "234" is blinking: System on. BIOS not execution. This is the transition state to POST states.


    And from what I can see... its not good news.

    Could be that your CPU for some reason is dead, or that your motherboard is faulty...


    You could try to clear CMOS:

    Besides that the next step would be to take the system 100% apart and inspect every part, and build the system back up again.

    This is one of the downsides of pre-built systems... When they one day stops working... can be a pain to get them up and running again (if you can)

  5. Thanks for the reply, and yes built one computer before. The error codes I have never known about, my computer build was over 10 years ago and gave me great service, this is not my build. I'm going to take it to a computer guy I know let him fk with it, Hey I found the video card burned right? Ha ha, I don't have the time to diy at this time.
