DVD LG drd8160b does not read DVD discs

I have a dvd reader LG drd8160B
It worked properly for 2 years. But it does not read DVD discs any
more for some weeks, only CD's. It asks me to insert a disc although
there is one in the player.
my config : win 2000, ram 256, HDD 40 G, AMD duron 1.2 Ghz, 1 CD
writer Sony
can you help me ?

Try using the drive on someone else's computer. if it still doesn't
work,it *might* be the DVD laser. DVD and CD technologies use different
wavelengths on their lasers, so there are actually 2 different lasers
in the drive. I don't think its possible to tell if there is a laser
failure, nor do i think there is a way to replace a problematic laser.
