Sony DW-d56a Help

Ok I got a Dell Inspiron 700m as a graduation gift last summer. it’s been perfect for the most part until recently, in the last month or so. It has a lot of trouble reading disc now, i’ve done the usual cleaning and such of the lens, but ut still has trouble. I even swithced to using SOny DVD’s and it still has trouble, the funny thing is that it reads retail DVD’s fine. But it even started to mess up my burn when i’m making an audio cd, which NEVER used to happen, and i’ve burned hundreds of CD’s.

Has anyone ever had a problem like this. I think I may need to update a drive or some firmware. Any points in the right direction would be helpful. Thanks.
