Windows locked up during boot sequence / initializing USB controllers

I have Windows XP Pro.. I currently moved my PC to another room. Now its locked up during its boot sequence while trying to initializing USB controllers. I can not ctrl/alt/delete, can not F8 to get to setup, can not reach boot in safe mode. I only have a mouse connected to a USB port. Have tried rebooting without anything connected a USB port. Any suggestions?

Hello and Welcome !

Get into your BIOS and try to reset to default values and see if that fixes it. When you moved the PC maybe the Hardware components might have loosen. If possible open your Tower make sure all are connected properly for example the hard disk the cables connected to your Motherboard etc. just remove it and connected back, dust your tower. Also inside the Motherboard remove the CMOS battery and after 2 mins put it back.
