I downgraded the kernel to 2.6.32-24-generic and so far I have had no problems even I left the computer turned on for more than a day. Before it was happening within few hours. I'm almost sure I solved my problem temporally. if someone else could confirm the same behavior, then it could be easier to see which differences were made in the kernel between those versions.
