I have a HP a6683w 2.0 GHZ 2.0 GB Windows Vista Home Service Pack 2 32 bit computer that is having issues with the cd/dvd rom. I can put in a good cd and it spits it out and says please insert disk when i try to read from it. I have bought a new SATA drive and it does the same. I do not want to format or reload windows if at all possible. I have done the Microsoft fix it and it did not work. i also have done the registry fixes found online and that did not work. Any and all help would be greatly appreciated.
