In device manger it does not show,also primary and secondary ata controller have a yellow exclamation mark. Someone told me go into safe mode remove maincontroller this did help.I have also been into every microsoft site i can find,they are telling me to add lines to my autobat.exe and config.sys. This does not work. What can i try!!!!!!
