I have recently upgraded my motherboard along with a new CPU, and now my LG DVD burner is recognised by the system, but will not run any programes or play any movies. It see's the files, but will not read correctly. Is this just a driver issue, or might I have damaged the burner when I upgraded?. I have removed all of the drivers manually and re-installed everything from scratch relating to the DVD burner, and still it will not work properly...!!! What can I do?!!
