I'm sorry for my bad English. English is not my primary language. :-)
@harper89:
Yes, PC2 was connect to the internet, but my computer didn't. I try to re-install my OS and update my motherboard drivers and my PC is fine. I also read my DVD Rom manual book, and it tell that the drive would install the driver automatically. But, the problem is same, my computer still can't read the disc. What kind of "device" do you mean in device manager?
@wizlog:
What kind of drivers I should install on my PC? I think my DVD Rom has been install the drivers on my PC automatically as it said in the manual book. And when I click my computer, it show a new driver (something like this E:/DVD-ROM).
