HELP! Pioneer DVR104

I Have TRIED to install the Pioneer DVR-104 DVD Writer on my PC.
Alls fine, IDE is recognised Etc Etc. But when Windows boots and finds my DVDW it also finds a CDROM, which there is none of! shortly after finding this Phantom CDROM Windows reboots, and it just keeps on doing this over & Over Again (ANNOYING)

For your info, the drive is on Primary IDE channel with no other drives attached, Running Windows XP on a XP2400CPU, 80gig HDD 512MB Ram.

Someone help me before I lose my mind!
