So i’ve ran into this issue on a few occasions while playing halo reach on the PC. So the way that it crashes is after a game, when everything goes black before the loading screen, the screen stays black. I try to tab out, doesn’t work. I try pressing alt + F4, doesn’t do anything. I Try pressing Ctrl + alt + delete, and it works as normal. From there i have the option to open the taskmanager, but when I press it, it goes back to black. It basically forces me to restart my computer. I don’t know if anyone has run into a similar issue. It’s not frequent in my experience but I thought point out the existance of this problem.
