GSA 4160B doesn't want to burn anything

I’m a girl…with a problem…so bear with me. (and I’m new here)
So I’ve had the 4160 for a while now and it hasn’t given me any problems, now all of a sudden, when I need it most, it doesn’t work.
When theres nothing in it, the computer (running XP) recognizes it as a DVD-RAM, as soon as I put a blank DVD in it, it turns into a CD drive. :confused: I’ve tried updating the drivers from the LG website but I get an error.
I’ve tried different DVDs, they’re not a new brand or anything, I’ve been able to write to these ones before.
Any Ideas???
