A new dump if it can help. Well, the dump start with a hibernation, he computer came back from hibernation fine. Did some reboot to try out alternatives and then let my computer turned on overnight. Even though the computer was not doing much task (simply turn on), there were a "slow to respond" issue about once every hours :s.
