Dave-maybe this can help? Windows loads all of the installed drivers into memory at the startup. A driver may refuse to load if the device for which it's designed isn't functioning or turned on,or if the driver isn't properly installed. If you remove a device make sure to remove the driver files also,even if it doesn't make an error message,it could be taking up memory. Driver errors can be also caused by hardware problems.-daŽyl <<<Dave Gibson wrote>>>I get the message "Error, An I/O Subsystem driver failed to load. Either a file in the i/o subsystem directory is corrupt of the system is low on memory." ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com "Hold No Punches.."
