In the boot menu, what is the boot order? And do you see your hard drive there? How many hard drives do you have in your computer?
What exactly does it say when you're in the boot menu? Try to type out everything that is listed.
Make sure the hard drive where Windows is installed is at the top of the boot menu. If it is, try pressing F4 to boot default and see if that works.
Make sure your CD drive and floppy drive does not have any media in them before you power up your computer.
Also check to make sure all the cables inside are securely connected.
After you've done all of this, what you can try is running a hard drive diagnostics utility to see if your hard drive is faulty.
Follow the instructions on this site to create either a bootable floppy or CD diagnostics utility.

If you ran the diagnostics test and it resulted as a faulty hard drive then yes, take it to a comp shop if you're not sure on how to replace the hard drive.
