Im playing raft survival and when i downloaded it i started it and after i selected the resolution and started it there is a screen made with unity and raft survival and after that my screen went blue with white letters and my computer restarted. I cant even get to main screen. What do I do?
That looks like the infamous BSOD (Blue Screen Of Death). Sounds like your comp crashed. If you see it again, check the error message and then Google it. Could find the culprit and how to fix it. Usually the culprit is a virus, but it could also be a hardware problem.
