I dont have a clue ...during boot up, my laptop flashed a screen reading (something like) "checking file system on c:
type of file NTFS"
and then gave me 9 seconds to allow or not...had no clue so i let it...WOW
it started checking and quickly showed a full screen of lines reading "inserting an index entry into index $0 of file 31752" with the last line just blinking...forever. i finally shut down by holding the power button. when i restarted, at the option to not check for consistancy, i said no. When desktop opened, i was flooded with alerts that many files were corrupt and unreadable...i would guess at least 50. i ran Eusing registry cleaner and after that i was left with only 2 alerts...one related to a fonts tff file,(c:\windows\fonts\margett.tff) is corrupt and unreadable, and the infamous c:\$extend\$ObjId is corrupt and unreadable.
in google, this seems to happening a lot. i hadn't used that computer in quite a while, so last week i updated all of my security programs...didnt seem to cause any probs at the time.
any advice would, of course, be appreciated.

Hi Jefffox and welcome to Bleepingcomputer
Take a look here: http://answers.yahoo.com/question/index?qi...06064049AAPZrxs and here: http://answers.yahoo.com/question/index?qi...26170751AA6AjdT

Are you having something that looks like this: http://en.wikipedia.org/wiki/Chkdsk scrool down the page until you see a typical results.
Does it look like that? Before you shut down your computer what does the results say, Does it JUST say inserting an index entry into index $0 of file 31752.

I would run chkdsk /r on that partition.

Chkdsk /f is the system's utility for repairing problems such as it seems you might have. Chkdsk /r (additionally) recovers data from bad sectors, as well as doing the 3 main fixes done by chkdsk /f.

The equivalent of chkdsk /r can be run from My Computer by using the Graphical Version procedures outlined in XP Chkdsk, Using the Graphical Version (My Computer) - http://www.updatexp.com/windows-xp-chkdsk.html

Put check marks in both options (scan, recover) if using the Graphical Version...and let it run to completion.

'preciate the feedback...yes, it just says "inserting an index entry into the index $0 of file 31752"
i ran dskchk again as you suggested, and it hung up again...when i checked the log (after i had to shut down using the power button, and rebooted, the log had no entries related to anything...still get constant warnings about the $Extent\$ObjId being corrupt and unreadable. what i dont have much of value saved on the hard drive...and all my programs are still available...would reformatting the drive help, and would it have a down side???

Just a thought, but if chkdsk is generating repeated errors, one possible cause is a failing/dying hard drive. Try a diagnostic utility from the manufacturer of your hard drive (usually free) to see if it's the disk itself
