Both of my drives (one is a 56x cd-rom and the other is a samsung combo dvd cd-rw) will not read a disk. they will read and play an audio cd but nothing else unless i reboot or log/out - log/on with the disk in the drive, then it will read. Could this be a mother board problem. I've tried changing the autoplay options and nothing. I'm running winxp sp1a and have an asus a7n8x deluxe motherboard. any suggestions will be appreciated. thanks
