    Need help determining if this is a Power, DVD, LCD, problem...

    I've searched to see if there was anything that is remotely similar to my problem, but I'll be honest, I don't know exactly what key words to search for, and my search has turned up empty.

    First off, here are my system specs:
    - Travla C137 case
    - Mini-ITX VIA EPIA M10000 Motherboard
    - Embedded VIA C3 1Ghz CPU with Fan
    - 512MB PC3200 DDR Ram
    - Hitachi 30GB 2.5 Hard Drive
    - DVD/CDRW Slim Slot Load Drive
    - Creative PCI Sound Card
    - OPUS 150W Power Supply inside Travla Case (On hot bench powered by regulated power supply 13.8V 3-5 amps)
    - PCI 4 port USB Hub
    - 7" 700TSV (Plugged in via AC adaptor)
    - 9/06 RR build
    - BMV2 skin
    - MPC (default installed)

    So here is a description of the problem:
    Every now and then (not always), I'll hear a "click" and my computer goes into the following state:
    - mobo is receiving power (mobo power LED is on, fans are on)
    - LCD behaves as if no input (Get the "Power Off" message on TSV)
    - Opus fans are still working, but LEDs "LD1" and "LD2" turn off on the Opus
    - No response whatsover from the PC

    First instance of this happening is during DVD playback. I don't have a reset button (yet) so I have to cut all power (mobo, opus, and hot bench power supply) to restart the PC. If I leave it alone for 5+ mins, everything will boot up once again. If I only cut the power to the opus and mobo (12V and IGN), it'll return to the state described above.

    Can some please help me figure this out? What keywords should I use in my searches? What specifically should I check? I've checked all my wiring and I cannot see a bad ground, chaffed wires, or anything.

    I'm at the last leg of my setup, after this, I'm ready for installation into the car.

    Your help would be greatly appreciated.

    TIA!

    Wow that's wierd. I accidentally hit the hibernate button and system went into hibernation. When I tried to bring the system back, it did what I just described above. So, I had to cut all power once again. When it rebooted, it came back up from hibernation.

    Does that mean that it's a Opus issue?

    Sounds like it could be an Opus issue. Do you have a different power supply you can try out (maybe a plug in unit)?

    Otherwise, it also sounds like heat. Just load mother board monitor or any of the temp monitoring software on it and see.

    I'm not much of a Windows guru, but I thought there were crash logs you could look at?

    I would first look at the PS you are using to power the Opus. You mention it is 3-5 amps. I don't think that is enough to power the OPUS. I would use AT LEAST 10 amps, though you may not need it. My system, draws about 6 amps when running.

    Try that, and let us know.

    It could also be a heat issue, but a system not getting enough juice can do WIERD things.

    Hmm, didn't think about that. When the system was using a USB soundcard and USB 4-port hub, I didn't run into this sort of power problems w/ the hot bench PS.

    I'll go and pick up a better PS for the Opus and see if the problem persists.
