I think I fan tai sui

Strange things have been happening to me for the past few days, like while I was typing a new entry this noon, the "Windows Explorer has encountered a problem and needs to close, do you want to send an error report?" alert suddenly pops out of nowhere, and caught my unsaved entry by surprise. Or how about my QD which was suppose to have broke down, but works like it is brand new at the Nokia Care Centre(coincidentally also this afternoon), and then only fail me again after I returned home?
