ANOTHER setup. Before plugging it in the case, it came on. Put it in the case, did not come on. Took it out the case, did not come on. Played around with it outside the case, came on. Put it back. Didn't come on. Tookit out. Came on.
Put it back in and just screwed it down, inserting RAM, and video card only. It came on. Plugged in other devices. It doesn't come on.
By "come on" I mean power up but no display.
Also, all the tests taking it out and putting it back on, only ram and video card were attached...
