Has this computer ever worked, or is it a newly built unit that you just got put together? Is the Hard Drive newly installed, or has it had an operating system installed on it before?

its all new except for my cpu, and yah the hard drive is new also, its like it wont boot off the hard drive. and before wen its loading the xp install thing, its at the blue screen where it says press enter to install windows xp, but i couldnt click enter, no buttons would work, an its not the keyboard, i have to reset the cmos when it does this. -2800+ at 2.1ghz -5900se 128mb -2x512 of pc3200 dual channel at 400 -DFI lan party ultra B nforce 2 NICE RIG!!

I've seen this happen tons of times. Go back through and make certain everything is plugged in properly. Check for bent pins. Check, that the Drives are "mastered" properly. Get the book out and Double Check what you have already checked 3 times before. It sounds like you have a simple jumper mis-jumped, or a wire mis-connected, or in a rare case, a bent pin. New stuff has a coating that has to be worn a little to make a good connect, so unplug everything as you check it and reconnect firmly.
