    Trying to bench test... won't boot! HELP!

    Hey everyone. I've got my carputer hooked up to a hacked ATX power supply and I am trying to bench test it to get my software up to snuff. I am using an M2-ATX and an M10000 motherboard. When I power on the PC, the fans will start spinning and the HDD LED will light up, but the computer won't boot! All I get on the monitor is a 'Check for Signal' message. Anyone have any ideas?

    Test the setup with a non-hacked PSU. If it still won't boot, slim it down to cpu and memory. Does it post? Any beep-codes? Hope some of this helps...

    Well all I did was ground the PS_ON wire on the PSU so I could run the M2-ATX off of a molex connector. I tried taking the hard disk out but that didn't change anything either. How would I know if it posts? And what are beep-codes? I don't even have a speaker hooked up to the mobo.

    post means Power On Self Test. It is all that crap that comes up on the screen (CPU, ram check, drives installed, etc.) When you say it won't boot, that sounds like it is having issues with the OS not loading. I think you mean it won't post, as in nothing shows on the monitor when powered on. Beep codes are used to diagnose post/boot issues. Certain numbers of beeps mean things like "ram not installed correctly" or "video card not connected" (not an issue on your mainboard though). Some mainboards have a tiny little speaker for beep codes, not sure on that board though. I would test it with a PSU that is normal, if it works then the issue is with your "hacked" PSU. If it doesn't work, then look at the mainboard/memory as the problem maybe...

    If you aren't familiar with POST and beep codes, then I'd think that building your own PC (whether for the home or the car) isn't the best of ideas. Those are some pretty basic fundamentals of configuration and troubleshooting.
    Have you looked in the FAQ yet?
    How about the Wiki?

    Ok I will try skipping the M2-ATX and powering it directly with the home PSU and see what happens.

    Well I skipped the M2-ATX and it booted right up and started running Centrafuse. I guess my M2-ATX is broken then?

    Or you didn't correctly setup the ATX supply to provice the M2 with power. Take the M2 and the MB out to the car, and test it on the car battery, and see if it boots. If it does, you have a problem with the ATX supplying the M2, if it does not, then it most likely is the M2.

    I'm learning a lot. I thought it would be best to put it in the newbie forum too. Atleast I got that part right?

    This picture shows how the previous owner of this set-up wired the M2-ATX to a plug for a molex connector.



    This picture shows how I modified the home PSU to always be on in order to run the M2-ATX off the molex connector. You can see the green PS_ON wire is cut and tapped to the ground wire.



    I got the information for this from here:

    Powering the M2-ATX Inside

    Did I do any of that wrong?

    What a day... the power supply I was using mysteriously died, so I hooked the white and red wires from the M2-ATX together and put a long wire with them, and put a long wire with the black M2-ATX wire. I took the M2 and the mobo out to my truck and hooked them to the battery. It sounded like the computer was booting up completely! Not like when I had it hooked to the home power supply where only the fans were running.

    So I guess my M2-ATX is still good. Now I just have to find some way to run the computer inside so I can get all my files and software onto it and running! Anyone have any ideas what I can do?
