    I am about to go crazy here . I turn the the computer on and the pwer supply starts up , I hear the hard drive start up , etc . , but it's like there is not a video card even installed . I get nothing . I changed the video card out with a known good video card and same thing . The power supply is acting a little strange . As soon as you plug the power cord into the back of the computer the computer comes on and starts powering up . Could the power supply be causing the no video ? Thanks

    Hi nitro237
    Unfortunately it could be lots of things. Usually when I have seem this it is not the power supply. First reseat all cards,connectors,memory DIMMs and processor and recheck your motherboard jumpers. If that doesnt work unplug your extra cards and drives and try to get a display with just the memory and video card installed. If no display then its down to processor, motherboard, memory and power. BOL

    Does the monitor work on another computer?

    Hi nitro237
    I know you haven't changed anything but sometimes they just come loose and need to be reseated. By the way if you hold the power button in for about 6 seconds it should power off. If another computer is available you could try your memory and processor out in it.

    I had computer where the power supply gave up, replaced it with a supposedly new power supply and it did the same as you are reporting, mainly turning itself on as soon as the power lead is put in. It turned out to be a faulty 'new' power supply, as soon as i changed it again, everything worked fine.
