I have an LG dvd rom and recently I bought an LG external dvd writer.The problems are that both my dvd rom and external writer cant read cd/dvd's on my pc it also causes my pc to freeze. But the external works normally on other Pc's. What could Be the problem
Most probable is your drivers. Go to your device manager and see if your CD/DVD has a yellow exclamation mark. If it does then go to LG's website and find the correct drivers for your OS and models and download them. Remove any conflicting driver and load the new ones.
