Same here.

You could have a common problem with some old games on windows, specifically with Windows Games Explorer. I had the same problem with Nox, Undying and Oddworld. Basically I launched the game, nothing happened, BUT my CPU load was 100%.

Everything is explained in this discussion:

I solved the problem using the file .bat in "RESOLVE IT FINALLY! Game Explorer AKA rundll32.exe problem with Games!".
