Hi. Here's my problem. My PC with Windows 8 Pro doesn't read any kind of discs. I first tried a movie then it reads, a little disc appears on the cursor which means that the disc is being read. But all of a sudden, it fails at the end and doesn't read the disc. Even a bootable disc, it just stays black with a blinking line then it fails to read it as well. No errors or messages, it just proceeds to the Windows 8 loading screen. Any help?
