How do you know when it's time for a new laptop? 7 years old machine

4. When it stops working or, perhaps just before...

I had noticed my seven yo laptop doing such things since the hack and I started doing the disc cleanup evey time I close the browser. It's amazing how much stuff follows you home from the intertubes. I not only do the initial cleanup but I rerun it with the system cleanup too, there's a pile of crap in there. Now, the only time it does that is when some huge thing is trying to manipulate my device or when it is conducting the cleanup search.

I have to do some air pressure treatment now that everyone's mentioned it and a twinge of guilt sets in...
