    Exclamation Newbie to the forum... and already with a problem!

    Hi all,

    I just registered to this forum, although I've been browsing thru it for about 3 months now. FYI, I am so far the ONLY person in Egypt to have an MP3car!

    My problem is this: My Mp3-puter is up and running in my car, but everytime I hit a bump at speed, it resets! Very annoying, let me tell you!

    BTW, I'm using a Pentium Celeron 366 with a seagate 13GB hdd, and an ATI all-in-wonder 128, and an SB pci 128 for sound. And I have a small Casio lcd tv up front. I am using a 300 watt inverter I got from RadioShack (NO noise whatsoever!) to power all this. The inverter is hard-wired to the battery with a fuse, and it turns on with a relay on the ignition.

    Any suggestions?

    I would check all the wires that involve the computer. When you hit a bump a power wire may be coming lose. It could also be your inverter, but it sholdn't be since it is designed to be used in a car.

    I had something leaning up against my memory, and when I hit a bump, the memory got knocked out of socked just long enough to crash windows.

    Also, make sure nothing grounds out when you hit a bump. I also had a problem where the motherboard touched the side of the case during high speed cornering ( ) and reset the comptuer.

    Cool

    Assuming that all connections are good and the system is not shorting out, I would consider how your hard drive is mounted. If you are hitting really nasty bump it could certainly cause the hard drive to literally crash. Of course this will bring about serious problems sooner or later with bad sectors. If you haven't already you might want to consider packing the hard drive in the foam that they use to ship the hard drives. This could help cushion the blows. Good luck.

    I wouldn't enclose it in foam. It would overheat very fast. I think the best way is what Aaron Cake has. His entire box is cushioned by springs. That way the hard drive takes less of the blow. You could use the foam as long as the hard drive was cooled some how......

    Guess I didn't tell you about my recent HD failure, eh? hehehe...I'll post about it in a few minutes...

    However, the springs do work very well at shock protecting things. Just remember: if your car has a stiff suspension, extra steps (ie. laptop HDs) will be necessary.

    Hot glue the RAM in place. That is most likely the problem. I had a tab on my old mobo that was kind of loose so I couldn't get the computer to start and run unless I physically held the RAM.

    Question

    Thanks alot for all the feedback, guys!

    I'm pretty sure it's not the memory, since the brackets are pretty firm, and nothing is touching the memory chips. I'm also sure that the mobo is not grounding out, since it is screwed in place quite solidly. And I replaced all the household plug connections with spade connectors, so it can't be that either!! I'm running out of options!

    Oh, and my harddisk is mounted on rails in a vertical position allowing it to move up and down, supported by foam from the bottom. So far, it's giving me no problems, but I know it's too early to tell...

    Is this problem that I'm having common? It's very frustrating!
