All boot disks either freeze or crash on boot.?

Ok so i've been having a problem with my computer not going to go into too much detail about that since that question is still pending on here. But while trying to fix that problem i noticed that everytime i try to boot from either a windows 7 disk, windows xp home disk, or windows vista recovery console disk it freezes. Windows 7 freezes at the windows starting screen, xp home goes to bsod after loading all the files and vista recovery console freezes at windows loading bar. And safe mode hangs at disk.sys. Any ideas on this would be great and i'll give best answer to anyone that help me with this.
