My laptop is 5.5 years old and is really, really slow - web pages freeze, it can take well over 30 seconds to load a page, plus it makes that whirring noise like it's having to work really hard. It often comes up with a message saying the internal memory is almost full, so I uninstalled some things I hardly use but it's not made much difference. Today it's been terribly slow, to the point that I could happily chuck it out of the window.
I can't afford a new one so is there anything I can do to make it work quicker and maybe help it to last longer? However, I'm not very technical so please don't ask me to physically take it apart!
