For no apparent reason I had my laptop running 8.10 freeze completely. I waited for awhile then manually shut it down. When I tried to turn it on again, I found that nothing would show up on the screen at all.
The screen was entirely black but after a few tries, it began to flicker. Eventually I was looking at a very low quality image of the normal start up screen except it would flicker on for a less than a second then flicker off again for more than a second.
I eventually saw a dialogue telling me that there was a graphics profile issue but I really could not do much about it.
I am a college student and my laptop contains all the work for my classes. Figuring out this problem quickly is essential.
