First reconnect both connection to harddrive power cable and ide or sata cable. Make sure harddrive is set as master you can set it as master with jumper settings on harddrive. Then when you power up the computer press F1 or F2 or del or ALT+F2 to enter in bios then you can see bios setup on screen make sure harddrive is recognized there. Reconnect RAM memory. Let me know if you need further assistance. Thanks for using FixYa.

P4X400 motherboard bad are there any replacement boards avalable?

Any motherboard with the same FSB speed and a Socket 478 should do.

Check out eBay:

Unfortunately the Soyo P4X400 seems to have a FSB quite long in the tooth: from 100 to 133 MHz.

You might be forced to upgrade the onboard RAM.
