    I tested with a DMM this morning, I only had time to test the rails, I'll jumper with the ATX cable later on today after work.

    I got a full 12.20 v on the 12v (Yellow) rail and No life at all on the 5v rail I can guess that that is NOT good.

    I know how the grounds work and I double checked the rails. [ o o o o | o x o x | x o x o ]

    I have a 80gb toshiba labtop hard drive, Rosewill Bluetooth dongle, USB audio, wireless keyboard, liliput. The audio and liliput are pluggged in at the end of a 6ft usb cable/ with a 4 port hub.

    Also a pccard, wireless network adapter.

    also for the moment of diagnostics I have most if not all usb devices unplugged.

    He didn't say the RAM popped out.
    He said that the RAM was specc'ed to the board and the whole setup pooped out (as in crapped out or quit working).


    The fact that you get squadoosh on the 5v rail is certainly the problem.
    Have you looked in the FAQ yet?
    How about the Wiki?

    With the M3ATX, the jumpers aren't going to make a difference as far as voltages. There is no jumper to disable 5v output.
    If the M3 isn't outputting 5v, the M3 is faulty, plain and simple.
    I applaud your diligence in troubleshooting, but you're delving deeper than you need.

    I did some tests with my DMM and did the fake turn on thing and all I had was the 12v again, nothing lower than that, thanks for your help.

    gonna get a new one.
