hi have you try to verify your disk first?. check if there is any error on your HDD first?, hope that helps cheers!

As you are testing a boot volume you're only able to verify & repair permissions not disk structure issues. You need to boot from a different disk to test this disk out properly.

Did Apple open up your system? If they did, you were very lucky you were able to pick up the system before any water entered in, as that is the usual killer.'

If they didn't opened the system up to see if any water entered then I would strongly recommend doing so soon as you likely have corrosion slowly eating away causing these problem and it will get worse. Let us know if you do find any so we can guide you on what to do to clean things up.

If its just the hard drive you'll need to find your original OS install DVD or create a bootable USB or external hard drive to properly test your internal drive. But even before you start testing things have you made a backup of your apps and data files? in the process you may loose access to one or more of them or may need to reformat your entire HD.

Plug in your external bootable drive and using the boot preference select the OS on it and restart. Then launch Disk Utility from your external disk and check you your internal disk using the repair option. You may need to do this a few times to solve all of the errors. If it can't repair the disk you can try reformatting it, if it tells you it can't repair the disk then it's time of a new HD.
