I have windows xp professional, whenever i put a cd in either of my dvd-rom or dvd-rw drives, it does not autoplay, and when i try to access the cd in the explorer, it displays the files on the cd, but when i try to run an exe file on the cd, i just get the hourglass on the mouse and it does nothing. When there is a cd inm the drive and i click on my computer, it does not even display the icon showing that there is a cd in the drive, this is not an extremely old computer, it is actually relatively new, and i can play a dvd, but whenever i try to install new software it lags the whole computer until i take the cd out, everything goes back to normal, please help, (by the way, the dvd-rw drive is brand new, so it isnt that)
