My T61 freezes when AC unplugging

My 14'' T61 freezes (using win 7 64bit) in couple situations: when plugging or unplugging the power source, when closing or opening the lid or when playing a video in full screen mode. It doesn't happen every time I do the mentioned actions, it's random. Sometimes it freezes just without any reason. I don't know if it is a software or hardware problem. Do you have any idea what could it be?

Thanks for your response.

If you use RM-Clock, set higher voltage values or remove it.
