Hi, my pc is making a disc kind of sound, kind of like an xbox 360 when first booting up a game, however theres no disk in the drive. The main culprit I think could be my ssd or hdd, and it only happens for a minute or two after it boots up, then its just goes away, its not too loud, which means I cant really tell if it dies down or just goes instantly. Any help with locating this sound would be great. cheers.
