I dropped my laptop, now have the error C:\clfs.sys

I accidently dropped my laptop on to its side. I turned it on and i was on skype and google for a while until i tried to search for a file and it froze and the a window came up saying somthing about Windows crashing. I did the little error test thing and it told me that the file was un-fixable. I don't think getting the disc to make it return to the factory setting would do anything because its corrupted i think. If you have any suggestions, please tell me.

Loose Hard Disk Check:

The first thing to check is whether the hard disk is physically connected to the motherboard properly. To do so:

• Shut down and turn off the computer
• Remove the AC Adapter
• Remove the battery
• Hold down the power button for 15-30 seconds to close the circuit and drain any residual power
• Remove the panel on the underside of the laptop where the hard disk is housed
• Remove and re-insert the hard disk by sliding it away from the connector and then gently but firmly pressing it back into the connector (no screws should need to be removed to do this step)
• Replace the panel on the underside of the laptop to cover the hard disk
• Replace the battery
• Replace the AC Adapter
• Turn on the computer and see how it responds

Post back once these steps have been implemented whether the system is stable. Sometimes these crashes/corruptions can occur due to a loose connection.

Windows Corruption:

Check Windows for corruption. Run SFC /SCANNOW Command - System File Checker up to three times to fix all errors with a restart in between each. Post back if it continues to show errors after a fourth run or if the first run comes back with no integrity violations. Use OPTION THREE of SFC /SCANNOW Command - System File Checker to provide us with the sfcdetails.txt file if errors occur.
