You can run CHKDSK, without being able to boot into XP.
Use the XP recovery console, run either form the XP CDROM (if you have one
or can get one of same type as oinstalled on your PC, home or pro), or from
the multiple floppy disk set (free download from Microsoft).
In the recovery console, use CHKDSK C: /R (not /F). This may take an hour
to complete, becasue it also checks every byte of free space on the C:
partition.
Here are some links about the recovery console:

Plan B: If you built this PC using a retail copy of XP, use the "repair"
option built into the XP CDROM. This option is not available if you bought
the cheaper OEM version of XP. In that case, think about a "clean" install.
Repair means leave personal files alone (and installed programs). Clean
install means erase everything (on C

and start over. A clean install can
fix registry problems, whereas a repair install will usualy not fix them.
Both "refresh" XP files (EXE, DLL, etc). Caution: Should a repair fail
then you might need to do a clean install anyway. Thus, have a backup of
all important personal files. See Plan C prime below. Here are some links
about repairing XP:

Plan C: Use the recovery procedure that was provided with your PC by its
maker. This may be a boot option, or it may be via a bootable CD (or
floppy) that recovers from a hidden partition. If you forgot how to do
this, contact the PC makers support group (or website). Chances of losing
all personal data and installed programs = 100%.
Plan C prime: First rescue your data to an external USB drive, using any
one of several free "live" LINUX CDs. (The images are free downloads, but
you must burn to CD or DVD youself.) See following links; KNOPPIX is
particularly easy to use, but is a very large download:
