    I,ve got a thunder i7500 board with dual Xeon processors 2GB RAM, SCSI hard
    drives, and I'm using the intergraded video. The board will not POST. Any
    suggestions? I have been down to processor RAM and video only, and still
    nothing, no beeps no POST but I do have power. the fans are working and
    there is a blinking red LED (D32) when first powered on. But then after
    about 8 seconds of blinking it goes out and doesn't come back on.The monitor
    is know good. I've tried brand new RAM. But still no POST. Any help or ideas
    would be appreciated .

  2. My money is on the RAM. This machine is very finicky and you pretty much
    have to use two or four of the exact sticks Tyan recommends.

    I was having lots of problems with power supplies before I got good
    consistent post. I ended up with a Zippy Emacs 650W.

    You may want to try something more jiucy, so to speak. Pay attention to
    amp capabilities on the 12v and 5v rails.
