Can anybody help me. I have a PCG-V505CP laptop which has served me well for several years. It has started failing to start sometimes or it will just stop in the middle of doing something. I have to pull the battery out to kill it. When it is restarted windows doesn't think I closed it abnormally. I can find no error messages on the system or anything. Does anyone have any ideas please. I've tried all the usual things of checking for anything nasty lurking on the system, plus scandisk etc. Help help help
