My old motherboard died and I am using an ASUS PQ5 SE Plus as a stand in until my new Phemon gets here with Vista x64 SP2. Since I've made the switch though, I've run into several DVD/CD read errors and slow transfer rates. I've experianced these issues with the drives connected to the onboard IDE, and also while they've been hooked up to a PCI IDE add in card. I thought at first it might be my drives, so I got an LG SATA DVD-RW drive thinking all would be well and pullerd out the other drives and I NEARLY threw them away, but I had second thoughtys and just set them on the floor so I could test them in another rig. Well, I popped in a DVD-R a day after installing the new drive and Vista once again insisted that I insert a disc when I double clicked it in Computer. With all drives, Vista has displayed the DVD-RW/ROM and CD-R/RW/ROM icons while the disc it refused to read was in the drive rather than the default drive icon used when the drive is empty. I've exausted my resources on hand to resolve this issue - I've tried 3 IDE DVD drives and a SATA DVD drive as well (2 ASUS and 2 LG) - If it's not the drives, is it Vista or the motherboard?
