    That's a monster you're building there.

    What kind of hard drive did you put in it? I seem to recall my home computer failing the POST because I had a bad drive...

    So it is posting now? If so, go into setup, select the rom that you will use to be the first boot device. Put your Windows disk in that and go for it.

    ok so now it turned on and i installed windows and its all good put when i restart or shutdown and i turn it back on same thing happens screen black and no beep i shut it down and took out the ram put it back in worked... sometimes i had to put it in a different slot to work though it froze up twice too but i guess its because im running normal windows xp not 64 bit hmm so does this mean my ram is bad cause thats what im guessing
