    inverter making pc do werid stuff

    hiya all
    ive got myself a lil setup thqat i had installed a few weeks ago a 12" lcd and a p2 233 powered by a 300w inverter

    now running from house power everything is fine boots up works perfectly but when powered by the inverter every now and then it dosnt recognise the video card and i have to reboot it

    its damn annoying

    anyone got some ideas

    cheers

    how often does this happen?

    do you have access to a different video card that you can try?

    prolly every 2-5 reboots (btw its actually shutdown properly)


    its a lcd controler card and its the only one i can use

    nope sorry no onther inverters

    another thing ive noticed is that when the inverter is on but the pc is off the psu(atx) makes a weird buzzing noise

    dunno if that has something to do with it

    There's a filter circuit that you might want to cut out of your PSU. do a search on here for it and see what you can come up with.

    BTW - does your signature need to be 16 lines long? It's just a bit of a pet peeve of mine and some other people, when you post a 2 line message and have 16 lines of signature. You could just put it all on a couple lines. Just a thought

    If you have a good quality inverter you shouldn't get any problems like that. Perhaps it outputs a square wave rather than a sine wave?

    mr pcman,

    yeah the buzzing is due to the filter circuit on your ATX PSU having trouble with an inverter square wave output.... on my system the buzzing transfered into buzzing on the sound card output, in your case it might just be causing some video card trubbles?


    and yeah true sine wave inverters cost alot! but I have found all the square wave inverters I have used to be fine....

    Also, are you sure its the inverter? Its certainly a probable culprit, but could the card be coming slightly loose from the vibrations of the vehicle?

    its not the card coming out cause the lcd still power up from it

    and also because sometimes a simple reboot and it detects the video card


    ive just ripped the top off my psu and its weird like a early atx and it has a seperate converter for the 3.3v weird stuff

    looking at it now theres a big white squar cap across the power input and a transformer/filter thing in thepower line

    gonna chop em out replacing the filter thing with wire links

    cheers
