I am presuming this is on a 98 machine.
Try a forced "Normal" boot.
Reboot and hold down the F8 or Ctrl keys.
You should get the following screen menu,(use the up/down cursor arrows and select Normal);
1. Normal
2. Logged (\BOOTLOG.TXT)
3. Safe mode
4. Step-by-step confirmation
5. Command prompt only
6. Safe mode command prompt only
