Your PC is getting on a bit As software becomes ever more sophisticated and powerful, it tends to make increasing demands upon the hardware platform hosting it – in other words your PC. Now you can’t really generalise about these things but if your PC is, say, three or four years old or more, there is a fair chance that the latest versions of software are asking it to do things it’s perhaps not really capable of. Even if it can actually do what’s required, it may struggle to do so quickly and efficiently.
You’re going outside of its performance envelope A slight variation on the first theme arises when you have purchased a relatively low end PC and have placed on it some extremely complicated and resource-hungry software. It’s a bit like trying to take a very basic family saloon car and asking it to perform well in a Formula One race.
