    M2 ATX - EN15000 - USB - Problems!

    Hey i'am almost finish with my installation in my car... But as your guys knows, you will never finish

    My Problem is...
    When i start my car (cold start), the system is booting perfectly (some times windows change my display setting in bios to LCD, so i'cant see anything when booting into windows)

    When i shutdown, and start again, i get blank screen, when i pull my USB Hub (it's powered from M2 +5v Molex pin) and try again its working ok!

    In my USB HUB i have connected USB DVD (powered from M2 +5v Molex), Touchscreen, Ruwido Wireless Keybaord+Mouse, Bluetooth, the USB HUB is in front connected to the computer in trunk with 6m USB cable

    What can it be?

    more than likely your touchscreen is trying to start before windoes has the drivers in place for it

    so, turn on your touchscreen, after the computer has booted?

    I had a similar problem with mine, using the molex connector from the PSU to power my touchscreen. The computer kept restarting when it was plugged in. Then I changed the monitor wires to be powered directly from the car power system, and the computer started up just fine. I think the monitor was drawing too much power, and so too might your USB Hub. This is all just based on observations, but see if you can power it another way.

    No change! didn't help! But i found out that, when i only unplug the power to the usb hub, which i get from 5v molex its working!!!

    So it might be something with the 5v, but where else can i get the 5v??

    If you can't get it from the power supply I'd ditch the psu... I have the M2 ATX also w/ the Jetway C7 25w version in a VoomPC. I'm having issues w/ my USB DAC (crackling when powered by CarPC). I'll chime in later if its indeed low voltage on the USB.
