I installed a new graphics program on my laptop which is running Vista. As long as I didn’t restart the computer, the cd drive was fine, but as soon as I restarted the computer, my cd/dvd drive stopped working, in fact, it doesn’t even show up under my computer. This is the third time this has happened; it seems that every time I install this program, it knocks out my cd/dvd drive. However, while the computer is restarting, the cd drives spins, until it’s done opening windows, then disappears. Can someone please help me. Another question–is there some kind of lemon law for computers–I have a two year extended warranty on this thing and it’s been in the shop for this same problem twice already. Thanks for your help!
