DVD-R Vista odd boot problem

[AstroCat]

Something very odd I've started to notice with my new build. If I leave a disc in the drive and boot up sometimes Vista will boot to a black screen. This never happens any other way and otherwise the system is totally stable.

Why would booting with a game disc in the drive sometimes have Vista boot to a black screen? Any ideas on this very odd issue.

My specs are in my .sig

Thanks.

I would just disable the CDROM or DVD drive as being the first bootable device and just have the HDD be the first device to boot.
