CDRW Can't burn!

[MasterNe0]

I got a sony cd-rw crx1611.

For the last week or so.I haven't been able to burn anything with my burner.Before that,I could burn anything but now,whenever I put in a blank cd to get ready to burn,It doesn't read it and freezes the explorer windows that are opened.I tried different types of blank cds that worked before but now, none of it works.

I used Nero and the built-in window xp write wizard and none of it works.I tried to load a game cd and it works but when i tried to burn, it doesn't.

I got WINDOW XP SERVICE-PACK 1.
