eli5 – Why pc lag or slow down when severals apps are open but the cpu and memory are not used at 100%?

503 viewsOtherTechnology

I know that this might vary from case to case, depending on which PC and which app I have open, among other factors. However, I noticed that with all that I had open, regardless of the apps or games running, when the PC starts to slow down or lag, the CPU or memory is not used at 100%, but stays between 70% and 90% depending on the situation. What could be the reason?

CPU and Memory are only two resources that can be scarce. It can also be waiting on network, disk i/o, graphics processing, or waiting for locks on resources to be freed up.
