  1. Building a new computer for my niece.

    Sagitta Raidmax case w/ 450 watt power supply
    Mobo asus p5wd2
    p4 dual core 3.4 ghz
    2 gig ddr-2 ram
    evga e-gforce 7600 gs (she is not a gamer) (pci-x)
    dvd-rom
    dvd-cdrw
    floppy
    seagate SETA drive

    The problem is that initial power up, I get no signal to monitor. Card has been reseated, ram reseated..unplugged all serial devices. I have no built in speaker in the tower or even an extra one around. So can't hear post beeps.
    There is no additional power supply on the video card either. Seated in primary pci-x slot.

    Just have no signal to monitor. Everything is brand new, built today.

    any help would be appreciated.

    Hello and Welcome to Techspot! :)

    What's your PSU brand, wattage, and how many amps it delivers on the +12V rail?
    You can find that info on the sticker attached to it.

    Good luck!

    you said no power to the card? ensure the card is plugged in also.

    does your fan on the card turn on with the psu turned on?

    No power, as in no extra power adapter on the video card board itself.

    This is extremely weird.

    Ok, I disconnected everything from the mobo, except cpu, ram and video card. Boot up and I have video signal.

    Reboot with floppy plugged in. Video signal is there.
    Reboot with SATA drive plugged in...Video signal is there.
    Reboot with 1xDVDrom, video signal is there.
    Reboot with 2nd Dvdrom, video signal was there.

    Started installation of windows, got past the time setting and computer name part, went had a cigarette..came back..video was gone. Reboot, video still gone. Unhook everything but cpu, memory and video card...reboot. Video back.

    WTF!!!!!!!

    Psu?

    well, I think it is the PSU, or the video card, because either the PSU doesn't deliver enough power to the video card, or the card is burned out, why don't you try another video card. like a pci card
