Why these four questions
The problems that actually strand people on install day are, in order: Wi-Fi drivers (one brand in particular), graphics drivers (one maker's older cards in particular), BitLocker recovery-key surprises, and scanners, which use a completely different driver stack from printing. Processor speed and memory are almost never the problem. If this machine ran Windows 10, it's fast enough for Linux.
If Wi-Fi is the thing that flags, the fix is a USB adapter with a chipset the Linux kernel supports natively. Here's which ones. And whatever the result, the safe next step is the same: run Linux from a USB stick first, which tests everything for real without changing your PC.
What this tool won't do
It won't pretend a red flag is green to keep you excited, and it won't pretend Linux is wrong for you because one component needs a workaround. If what you actually need is to decide between staying on Windows 10, Windows 11, Linux or a Mac, that's a different question; the path finder handles it.
