My microphone has a problem sometimes where the volume on it will go extremely low and won't normalize until I reboot. So my friends told me that my mic was quiet and I restarted and went to grab some dinner.
When I got back, I saw the screen asking me if I wanted to start in Safe mode, Safe mode with networking, Safe mode with command prompt, If I wanted to start with my last known good settings, or if I wanted to start windows normally. I've gotten this screen a couple times before, and each time I would just tell it to start normally and it would. So I tell it to start normally and I go back out to the kitchen to grab a drink.
I come back to my computer and I see the same screen. I was like, alright, my computer must have frozen or something, so I told it to start normally, and it wasn't frozen. It got to the windows screen with the loading bar at the bottom and then a blue screen with a lot of text on it flashed up for half a second, before I even got to read one word on it, it rebooted my computer.
Nothing like this has ever happened before, so I asked a friend about it and she said she had the same problem with her computer when it was overheating. So I let my computer cool down for about an hour or 2, and I tried it again. Same exact problem, nothing changed.
