1)Try running Chkdsk for errors:
Go to Start>> Computer
Right click the hard disk that you would like to test.
Select the Tools tab
Click the Check Now button under Error-Checking. You may be prompted for an administrators password or confirmation at this point.
Select the option: "Automatically fix file system errors"
Select the option: "Scan for and attempt recovery of bad sectors". Selecting this option will perform a thorough scan of your selected hard disk and attempt to fix any physical errors on the drive. Depending on the size of your hard disk, this could take quite some time to complete. For best results, avoid using your computer system during this process.
2) If chkdsk didn't help you can try to restore your computer back to when things did work:
Go to Start>> All Programs>> Accessories>> System Tools>> System Restore
Select "Choose a different restore point"
Select a date and time that you would like to restore to.
Click Next to begin the process
In the confirmation prompt, select Yes.
Once system restore has completed the process, your computer will restart.
