I have a PC that seems to hang at almost the same time every day. I have checked for scheduled task from every application I can think of and none happen at the time of the crash. The only entry in the event log to show anything is wrong is one stating that Javaw.exe is hanging. The only clues I have are that the fan starts to make a high pitched shrieking noise, the system seems to lock up or work incredibly slowly, and that the javaw.exe application seems to start using large amounts of memory (over 800K.)
I have tried removing and reinstalling Java, replacing it with different versions, I have checked for any and every application that could be running an update at that time and nothing helps. Can anyone suggest other possible causes I can look at for this?
