ok, trying to play a dvd on my computer, first time since i downloaded 7. it sounds like its about to load, then goes silent. i try and tell it to play, but the dvd drive doesn't show up on my computer. I check device manager, it says that my driver is either corrupt or missing, I try and update, says it's up to date. I download a new driver from dell, try and install it, says can't find target drive. SOOO, I grab my windows 7 disk to see if i can install it from there, but wouldn't you know it, the disk wont run on my computer....someone please help me.
