I'm trying to do a disk check but when I do it manually it always exits halfway through and when I run the DOS program and physically enter chkdsk /F it says that ""access denied as you dont have sufficient privilages. You have to invoke this utility running in an elevated mode"

What does that mean?

Find Command Prompt in the Start menu.
Right click on it then select Run as Administrator.
Press Ctrl+Alt+Del to enter task manager and end the explorer.exe process.
Now try to scan

If this does not help try the next at your own risk:

Open regedit.
Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CURRENTCONTROLSET\CONTRO L\Session Manager
In the right pane find "BootExecute" and edit it.
It should say: "autocheck autochk *"
Now change it to "Autocheck autochk /p \??\C:"
This should schedule the chkdsk to run on startup.
Restart and let me know of the outcome as I haven't tested this yet...

Cheers
