PLEASE HELP ME: CheckDisk: Access Denied On Reboot

[Guest]

CheckDisk in XP SP2 can't access my system drive C: before or after reboot.
Message says unable to access, then system starts normally, BUT, I CAN'T BOOT
INTO SAFE MODE EITHER. The Loading drivers scroll down the screen, but just
never finish loading. I MUST Have A BADDIE. I Have Updated Kaspersky
AntiHacker and AntiVirus, PCTools Spyware Doctor, System Mechanic 6
Professional, WinPatrol Plus, SpyBot Search and Destroy. Everthing comes up
clean, but not being able to access Safe Mode is not helping me at all.
PLEASE RESPOND WITH WISDOM.

Disable or Enable CheckDisk Upon Boot (Line 82)
