Pioneer 111 - New Build

[unknownsidhu]

Alright guys, I need some serious help. I recently put together a new PC, and installed in it a Pioneer 111 from my old PC. The Drive itself is excellent, and has worked flawlessly in my old pc. However, I seem to be having problems using it in my new PC. The drive seems to only be able to read discs - and it does this without any problems. The problem starts when I use it to write. Ive tryed to burn audio cds, as well as .iso images, and either way the write fails. Ive tryed both IMGburn as well as Nero - and so far no luck. The mobo Im using is a Asus P5W DH Delux, with a Intel Duo E6400. Also just to add, Im given a number of different errors in IMGburn, one the disc has begun to burn. Such as "Device not Ready" & "I/O Error".

Anyone have any idea on what maybe wrong?
Thanks!
