• Start the computer in Safe mode.
• Click Start | Run, and type 'regedit' in the Open box and press Enter.
• Click Continue if the 'User Account Control' box is displayed.
• Find any of the following registry entries:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Msahci

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\IastorV

• Right-click 'Start' in the 'Name' column, and click 'Modify'.
• Type '0' in the 'Value data' box and click OK.
