    Hello all,

    Someone has given me three motherboards but i cannot test them! :(
    I have two dells but they are no use as the power buttons on them are just for dell boards.
    How do normal power buttons attatch? It would have to be one for any board and i can test all three and then go onto use it in a build! :D

    Do i have to make my own or can i buy one.

    Think thats all. all ideas / anything welcome!

    Thank you.

    Ok, so you will need to find the two points on the board that the power switch connects to. you then need to link those points with something metal, to simulate the action of a switch

    yeah, but that would let you test the boards. You could set up a normal momentary switch when it is in the case.

    the pins sticking out of plastic this guy is pointing to are pin headers.
    [​IMG]
    find the one labeled front_panel or similar. (there may be multiple headers, for USB or serial or audio or stuff. they should all be labeled) there should be a diagram printed on the motherboard saying which pin is which, look for the two pins corresponding to pw_sw or pow_sw or pwr_sw or something to indicate they're for the power switch. plug them into a momentary switch, or just short them with your fingertip to turn on the computer.

    if there is no diagram, just short random pins (edit:random adjacent pins.) until the computer turns on. there's no current flowing through anything but the power switch pins, so there's no danger of shorting the wrong thing.

    If the computer turns on, however, be sure not to short the wrong pins. :)

    And if using your finger doesn't work try something conductive - I use cutlery, usually a teaspoon.

    If you know what system the boards came out of, you can usually search for (system name) front panel pin-out

    i ran xp no problems for years on a dell PIII 866mhz. it's slow, but it should work. if it isn't, there is probably something wrong with your hardware.

    I have a 700MHz PIII machine that runs XP perfectly. Managed it with an 800MHz Celeron for a couple of years as well, that was...interesting.

    min requirements for XP is like 350mhz and 64mb of ram, so a CPU twice that of 700Mhz laughs in the face of xp's min requirements.

    Oh and i had an old compaq, with a PII 333Mhz that ran XP, sure media players visuals killed it, but who cares, we all use winamp or similar app's.

    That reminds me, that system to this date still runs, and its the most quiet system i have ever owned. stupid passive cooled PII cheesecake!

    That sounds like the XP install on that HDD of yours has drivers installed, in which case is why its causing problems.

    If you can try a fresh install with each board tested, takes time but it stresses the system, and you know its not a driver problem.
