First off to avoid confusion: I am manually restarting/shutting down my computer, it isn't automatically doing it on its own. Ever since about a month ago my computer screen has begun to flash before restarting or shutting down. I will give the command and immediately my screen will flash for a split second, return to normal, then flash again before completely the process. Some times it will even get to the blue windows "shutting down..." screen and then return to my home screen, flash, then shut down. Also, I don't know if this is helpful or not, but when it brings up the "programs that still need to close" window there won't be any programs listed. Then after it flashes for another split second "steam.exe." will appear in the list, followed by more quick flashes, and it will shut down. Any help and advice is greatly appreciated and let me know if you need any more information, thanks.
