help with PC not booting

I need some advice as to why my pc is not booting after I moved it 5 feet into a cabinet.
I unpluged everything to move it into the cabinet. After reconnecting all my devices I turned it on and it was working fine. I put a cd in to listen to music and after a couple of songs the machine locked up. Now when I try to boot the systen preforms a disk checks, finds no errors, acts like it wants to boot, then asks which mode I want to boot to, ie safe mode, last known config, or normal. I have treid each of these choices and all that happens is the entire process of disk checking begins. It keeps going around in circles.
I have tried reseating all the cables and all my pci cards thinking this might help, but I am having no luck with anything. Can anyone give me some advice as to what may be causing this mess. All I did was move the machine 5 feet. Help, I pulling my hair out over this.

(^^;?(I don't know how you moved it 5 feet, HDD is weak in vibration then it would have been damaged while moving.)

Chech the disk by powermax.exe from Maxtor. In critical case you must salvage data by all means.
