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!
