I using Vista 32 bit on a Toshiba Satellite A135-S4527 the problem is my cd no longer shows up in win explorer or in device manager. don't know when it happed as I haven't used it in a while but I can't use my cd at all. I don't think it's the hardware as it starts running as you start my compputer I can hear it spin befor windows log on screen comes up. I tried removing the filters but that didn't do anything and I don't know what else to do? Please help Me
