An “invalid system disk” error has several possible causes. Two of them will make you hope you backed up recently.
Four basic approaches to storing a laptop that isn’t being used.

Windows 10 made adjusting the size of items on your display much easier.
CHKDSK and Defrag are different tools for different purposes, and have different side effects. One is OK on any drive; the other should be avoided on SSDs.

Using an on-screen keyboard instead of a real keyboard might stop some keyloggers, but there’s no guarantee that other techniques aren’t also being used.
MAC address filtering is a technique that theoretically prevents unauthorized computers from accessing your network. I’ll explain why the theory fails.

Processors are generally available with what are called “multiple cores”. We’ll look at what that means, and how you might select which is right for you.
Intel’s Core i3, i5, and i7 processors present a headache-inducing combination of characteristics. I’ll look at what matters and then dig a little deeper.
Device-driver updates can come from several places. I’ll review which sources for driver updates are best, and where else you might need to look.
Chkdsk checks your disk for errors at a low level, requiring exclusive access to the disk to do so. “Chkdsk cannot run…” means that it doesn’t have the exclusive access it needs. I’ll review what to do.
Photographic images have a number of characteristics that we often don’t consider. I’ll review how digital pictures are constructed and stored and what you need to keep in mind when sharing or publishing.
Why do some chargers work faster or slower than others? We’ll take a look at some basic electrical concepts to understand what to look for in a charger.
