I have also had this same issue and I'll try to be as accurate as possible as to how it occurred in the chance that the developers may be able to reproduce it, if you need any other information, please reply and I'll try to provide it:
I purchased C:SL and enjoyed 9 full hours of it succeeding in creating a Megalopolis, and it was an excellent experience. Now wishing to further my experience with the game I installed some mods including the First Person mod and 25km2 Mod, upon loading a new city in a new map with these mods enabled my computer proceeded to fully shutdown and required a disabling of the power supply, and re-enabling simply to reboot. I figured it was perhaps an overheating issue, however upon monitoring my system usage and temperature (I use Speccy), it was only at 5% CPU usage, and sitting at ~36 degrees C. So I then proceeded to remove the mods I had installed and disable all pre-installed ones if they had been enabled. Same issue, hard shutdown. I did a little bit of research and found a forum that found it causes a Critical Kernel 41 ID Error in the Windows event log. I then proceeded to remove my old save game, uninstall, reinstall, and verify integrity of game cache through steam (all successfully validated), Still the issue persists, and it still continues to shutdown my computer. As far as I can recall, all that had changed was the mods being activated/installed and the process of starting a new city.
Thank you all so much in advance and to Paradox for such a great city builder...I would clearly love to play more....You'll find my system specs, windows even logs, and other pertinent information below:
