I'm having a recurring problem with my DVD-ROM and CD-ROM drives. It seems that after intially starting windows XP both drives work fine. However, after awhile, or using them once, then trying again, the drives won't read the disk. I thought that it might be a hardware problem, but the same thing happens to both drives, and the problem starting happening around the same time. If I reboot, then I can use them; however, after one or two times, the drives won't read the disks. I've tried uninstalling the hardware in Device Manager and re-installing. I've also tried updating the drivers. Nothing seems to work. Any ideas?
