What will not retain data after the computer is turned off DVD ram rom harddrive?

Technically, volatile memory, typically implemented as random-access memory (RAM), will not retain its data unless power is applied.
Note that "the computer being turned off" is an ambiguous statement. Most modern computers are always under power to some extend, unless mains cord and batteries are removed. This might include maintaining data storage in otherwise volatile memory.
Also note that most modern operating systems support 'sleep' or 'hibernation' modes, during which the computer is powered down to the extend possible. Data which would be lost (such as data kept in RAM) is stored on a permanent storage media, typically a hard disk, during this time, and is being re-loaded when the computer returns to normal operation. While the RAM has lost its data during that period, saving and restoring it makes it appear to have persistent storage.

depends on several factors- 1) if there is any data on that harddrive you need, TAKE OUT THE HARDDRIVE. 2) if the harddrive is less than 120 GB, and the above is not true, GET RID OF IT. 3) if the harddrive is working, and number 2 is NOT true, KEEP IT.
