Lg dvd problem!

ok, i built my pc one year ago and everything was working fine until i format the role thing, now i’m instaling everything again, including the cds that come whith the dvd drive ( gsa-4120b ) but the drive don’t work, don’t read or burn any dvd, but read cds and burn them normal. What i do ???

Install a proper dvd player software like powerdvd and a proper burning program like Nero.

i installed nero and power dvd, they come whith the driver, i instaled all the softwares that came whith it but still doesn’t work…
