TELL EXACTLY WHAT YOU HAVE. MacBook (old white case) is ancient. Is it OS 10.9.2 or 10.5.8?

Wild guess: too many forced-power off. That will cause file system errors.

Do all the normal routine computer checks....
– Boot to the "Applications Install DVD" by holding the D key for 45 seconds at startup.
– Disconnect all but the power adapter and test.
– Repair Disk with Disk Utility.
– Check for full startup disk (needs about 15% available space).
