Do note that Return to Krondor is NOT listed as being compatible with Windows 10, so if you tried to run it on that, strange things may happen.
Another possibility is a conflict with security software. Several years ago I first thought my computer was hanging when starting some newly installed games before realizing that Comodo wasn't recognizing them as safe and trying to prompt me what to do after the game took over the display, so I couldn't see the prompt and the system wouldn't seem to respond until I answered it, which I couldn't. So you may want to check that as well, thoroughly.
There were also other games that appeared to cause freezes because again they held the display after crashing (Lords of Xulima a few times, for one, I think also Disciples 1), so my computer was responding, but I couldn't see it, needed to learn to force close the game from Task Manager blindly.
Do recall The Witcher 1 causing what sure seemed to be a full freeze once, but not entirely sure there wouldn't have been a way around that as well if I would have tried hard enough.
