To run the check disk utility you will need a repair disc or a operating system disc. Put the disc in the cd drive and boot from it. You want to get to the Dos Command Prompt (Black screen with white letters) and type the following command: chkdsk /r Check disk will run well over an hour or two and you will notice the percentages going from high to low, this is normal. Let it run to completion. Then reboot machine. If check disk fails to solve your problem you might have to reinstall windows. Try doing a Repair Install that way you don't loose your data, documents, music, pictures, videos or programs. In windows xp you get to the dos command prompt by selecting R for repair when the options appear. In Vista and Windows 7 you want to get to the recovery console and look down at the bottom of the window for the Dos Command.
If after the check disk utility you are still having problems then you might have to reinstall your operating system.
