I have to different DVD drivers: LG GH20NS10 SONY AD-7240S and both of them I can't make work with windows 7. LG it doesn't even recognize the dvd I insert, and it freezes even if I just open "My computer". Sony it recognizes but everytime I try to play a DVD or click a data it freezes and I have to restart. But both of them are recognized in BIOS and by windows. I don't know what to do anymore. Already updated firmware for both of them. I tried start the pc without the 2 plugged together also. (one by time) My pc specifications: AMD Athlon 64 x2 5200+ 2x 1gb RAM kingston DDR2800 Asus M2N-VM DVI motherboard 2 HDD: 500gb seagate SATA 160gb samsung SATA ATI Radeon X1950GT Corsair 400w power supply I would really appreciate if someone can help me. And sorry if has been already solved before, i searched a lot here and outside the forum, and couldn't find the answer. Thanks!
