If you've got air conditioning / dehumidifiers running, it is possible that your room lacks the humidity required to "dampen" static electricity charges from building up. While it is always a good idea to make and break all the connections on your system occasionally, i would invest in a small meter that measures the relative humidity in the room.
As a side note, you might want to rig up some type of grounding post that you can touch prior to working with anything in your system. Some people attach a small metal plate that they attach to a convenient yet out of sight location on their rack or use one of the support rods on the rack. Grounding either of these and then touching it prior to handling your gear minimizes the potential for damage to your gear. Since static electricity can reach levels into the Kilovolt ( thousand + ) level, it is quite possible to whack something up in the matter of micro-seconds that it takes for static to arc from you into the equipment.
