Hi Janet May I ask why you don't switch it off at night? It can't do it any good continually working when not needed and wastes electricity and therefore costs more to run I use Ccleaner last thing before shut down to clear cache etc and find its much more reliable (fatal thing to say with computers I know :-) Perhaps giving it a kip each night will make it feel better with itself <g> Best wishes Nivard Ovington, in Cornwall (UK) >I am running Presario Laptop, Vista Home Premium. > > I do not turn the computer off every night.
