When moving the SATA cable or power cable or both may have shook loose from the hard drive with all the movement. The system is failing to find the HD and load the operating system when you power it up. Shows up as a disk boot error...no hard drive with XP OS found. Try opening the case and checking all the connectors to the MB and hardware, especially the hard drive's SATA cable.
