Doesn't Boot after New Install

After the OS Winxp has installed some of its files, it needs to restart to continue installing or to setup the installed files. As soon as the system diagnostics is over it should boot up to the new hard drive... where the initial setup had taken place, but it seems that it just stops there, the cursor on the top left of the screen blinking it seems forever. It would boot on the CD but not on the Hard Disk after it restarts itself. I tried the hard disk to another computer and it worked perfectly.  I had already changed my cables and even the power supply, well, it is still the same. So anyone can give me an SOS on this situation?
