    So I was using my Dell E510 and all of a sudden it shut off and the power light turned from solid green to flashing amber. The error codes on the front panel were 2 3 4. I looked this up in the manual and this is what I found:

    "A possible USB failure has occurred."
    "Reinstall all USB devices, check cable connections, and then restart the computer."

    I checked to make sure all the connections were secure. I replaced the power supply. The computer still will not turn on. I still get the blinking amber light with the 2 3 4 error lights.

    What can I do to make this work?

    When I contacted Dell they said that since my warranty expired that I would need to pay to talk to someone about what part I needed to replace. I'm really hoping someone can help out here.

    Dell E510
    Pentium D 820 Dual Core (2.80GHz, 800FSB)
    1 GB Dual Channel DDR2 SDRAM 533MHz (2x512M)

    My 1st guess would be that the motherboard has failed. The E510 used a BTX form factor board that had a high rate of failure. All Dell systems that used BTX form factor boards had a high rate of failure after 3 years or so. Intel discontinued further developement of BTX form factor boards in 2006.

    Here is another thread in this forum at the present time where a Dell BTX board is being replaced.

    Thanks for your help. Is there any way to confirm motherboard failure before I buy a new one? The light on the motherboard still turns on when I power it up, but nothing works.

    if nothing is working its possible that it is the board. it might not be worth fixing since the computer is 5 or 6 yrs old and boards arent cheap.unless u really want to keep the computer it might be easier just to get a newer used or brand new computer.hope this helps.
