    Question External DVD stops the PC booting

    I had a problem that my PC would freeze right at the memory check stage (before it even starts booting the OS).
    After several troubleshooting efforts I unplugged the DVD and immediately the machine unfroze and booted normally.

    My question is, could this be caused by too much power being drawn from USB as I have several devices (GPS, wifi, bluetooth, keyboard, mouse) all drawing power from the USB ports and the DVD is doing so too.
    If I power the DVD externally (direct from the car) will it solve the problem?

    It had a DVD movie in which I took out but it still caused the issue. I haven't checked the BIOS setting but it was working for months and I haven't changed anything in the BIOS since then.

    Most likely not. Mine did that randomly. Sometimes it was good for a week, sometimes it happened 5 times a day. Sometimes it would freeze at the BIOS, sometimes it would freeze at about half through resuming XP. I ended up putting a switch on the power line so I could cut power to the DVD without having to unplug it.

    I had an external 2 amp 6v regulator for it too, and it still did it. It was rock solid once you got into Windows though...

    I ended up getting sick of it, and switched to firewire. Haven't had a problem since. And i got to ditch the 6v regulator, as the firewire port powers it just fine. Luckily both my VIA board, and external enclosure had firewire ports, does yours?

    Yes it does. Perhaps that's the way to go then. How can I find out if the DVD is compatible (I bought it off ebay and it was just taken out of a dud machine so not too much documentation!)

    It has more to do with your external case than the drive.The drive just has an IDE to usb/firewire adapter. So, if you do have firewire you should be fine.

    If the enclosure has firewire, and your motherboard has firewire, use firewire. And get your cables from Ebay... Local places wanted like $35-40 for a 15' 6pin to 6pin. Got one off of Ebay for $8 out the door...

    My external USB drives was also causing my system to hang during boot and waking from hibernation. i found out that it wasnt the USB, it was becuase the drive was mounted vertically. I have a slot loading slim dvd drive, and apparently it doesnt like being mounted vertically. After I unplugged it, it works fine.

    Wierd. So it works fine if it was horizontal? Mine's always been mounted horizontally, so I know that wasn't it.
