Hi, new member here and I don't really have a high knowledge of building or working on my computer, so please bare with me. My old 4year old NEC DVD burner seems to have run it's course, so I purchased a new one, actually 2. A LITE-ON 20x DVD+R w/ lightscribe SATA burner and a Pioneer 20x DVD+R DVD burner IDE. I wanted to go with a SATA for the supposed increase in speed over the current IDE that was installed but after switching them out the sata cable that came with the Light-On model seemed a bit short to plug into my mother board and I didn't want to chance screwing somehting up. So, I went with another IDE model in the Pioneer thinking that I just had to reconnect the existing power and IDE connectors, which I did without too much trouble...lol The burner did power up (led light indicator on and DVD tray popped open). I also was able to download (after quite a bit of searching) the firmware update that was suggested when installing this Pioneer. But when I insert a DVD nothing happens. I went to my controll panel and into device manager which listed nothing in DVD/CD ROM devices. When I switched back to the orginal NEC burner my device manager listed my 2 previously installed players....... NEC DVD_RW ND-2510A ATA SONY CD-RW CRX230E ATA When I had the new burner installed Vista was telling me it detected no device and there was nothing listed in the device manager under DVD/CD - ROM drives. Sorry for the long story, I'm sure this is a simple matter to most of you guys, but I would greatly appreciate it if someone could shed some light on what I am doing wrong. I recently up graded my system... OS (Vista x64 Ultimate), GPU (FOXXCONN 8800GTX OC@630/2000) and added additional 2G DDR2 800 PC-2 6400 to 4G total. I have had problems with this area also that I seem to be getting slowly ironed out...i.e. BSOD, freeze ups and ramdom crashes...don't know if this can be inter-related with My DVD install problem.
