I am currently using a Lite On Cd/DVD combo drive, and I have a very annoying problem. Whenever it is accessed (opened, started, closed, read) it will make my computer lag tremendously! I can listen to a song or be in Ventrilo or Teamspeak, and whoever is talking, or whatever music is going when the drive is opened, will start to stutter, freeze, pause, loop, etc. I have speedupmypc and it says it is using over %50 of my computers power? I also checked Device Manager, and it is set to DMA if available. But the current transfer mode is "Not applicable" I have tried unplugging the drive, rebooting, reinstalling, etc. Nothing helps. I also bought a new combo drive to see if its just faulty, but it does the same thing. Oh and, Everest home says it is an SCSI Cdrom drive. Does that mean i need a special cable instead of using an IDE cable?
