I AM RUNNING WINDOWS XP PRO AND WAS HAVING PROBLEMS WITH INTERNET EXPLORER CRASHING REPEADEDLY AND RAN SOME MICROSOFT FIXIT PROGRAMS AND THEN DID A CHKDSK ON C: DRIVE WITH THE FIX OPTION. IT DELETED A LARGE NUMBER OF FILES THEN HUNG. I POWERED DOWN THE SYSTEM AND NOW WINDOWS CRASHES WITH A BLUE SCREEN OF DEATH.......  HOW CAN I RECOVER FROM THIS WITHOUT THE ORIGINAL XP DISK?     I TRIED SAFE MODE AND RESTORE TO LAST WORKING SETUP BUT DOES NOT WORK.
