So every time I wanted to start a program on this replaced PC drive I would get an error message. I'd have to hit cancel a few times and then everything would work. It was a bit annoying.
But Windows 10 fixed this. Or maybe it's just because I installed a new operating system so it re-did all the checks.
Things seem to run more slowly, though. Just a bit but even a bit isn't good. Maybe it's because my screen resolution isn't the same. When I installed this, the screen resolution defaulted to 640x480 or whatever and I moved it up to my maximum setting. I don't know if I had it there before. It certainly wasn't 640/480, though.
