Maybe this has also to do with Win 10. Don't know what version of windows you use, I still use the good old Win 7 64. No problems even with my old low spec laptop. Ok, I only did a bit of keyboard-test-flying, no missions or something else.

I avoid Win 10 like plague, although I'm already having Win 10 licenses. But sadly it will not be possible to stay with Win 7 in future with new machines.

No more drivers and even the install is a pain on modern PC's. I had to use an old PS2 keyboard and mouse to setup the system of my girlfriends son (very similar to the systems I still bought).

There is no native support of USB 3.0 in Win 7 and you need this to get your USB-keyboard and mouse running during the setup. On the other hand there is still a support for the old PS/2 , but here you need an y-adapter to get both running, mouse and keyboard. And of course you have to own a old PS/2-mouse/keyboard.
