My cd/rw wont write

Okay, I know that the hardware works because they all work great on my other computer, but this dell4420, will not allow me to write to a disk, I know I am doing it right because all three burners that I have tried, work just fine on my other. I checked the DMA and it is available, HELP PLEASE, I am so frustrated, I have been working on this issue for months now.
