Hi all Please can you help, my 11yr old has a e-system103a & I installed a sony g120a dvd drive in to it just over a year ago but now I have a problem which I hope all you guys can HELP. I install any disc nothing happens, I go to device manager & I get a message cannot load device driver may be corrupted or missing. Please can someone point me in the right direction as I only have a few days.
