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...

Seagate Barracuda 320gb sata

hmm yeah the motherboard has like little blocks and they can show numbers and letters and such and they both show "-"

 

[Badands]

ohh and i know that the screen works too cause im working on it right now with my other computer

 

[Badands]

hmm sorry i keep adding things like this i just remembered and thought it might be useful information yeah so its the first boot too so the hard drive is empty

 

[Badands]

update!!! i was messing around with it i read something on here bout isolating the bad component nad yeah i took off all the drives and nothing then i was thinking bout the ram so i took it and pt it in another sot and it worked it booted up and beeped twice on the mobo the little thingy posted 7F and i looked it up in the Manuel and it said "POST error check" "Check POST error and display them and ask for user intervention"

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
