Yes you can, but be aware that you *may* be seeing the early signs of a
failing hard drive.

Boot using your WinMe Startup (floppy) Disk and at the A:\> prompt, type:
scandisk c: (Note the syntax - space between k and c followed by a colon)
Then press return.

If it shows errors, do not let it 'fix' them or do a Surface Test until you
have backed up your data - you may need professional assistance if you're
not sure how to copy or recover your data files.

However, if you are prepared to lose data, then let it repair errors and do
the surface scan.

Hopefully - and with a bit of luck <g> - it may even fix the problem.
