For the last few days my computer has been giving me a blue screen that automatically restarts my computer. So i changed some setting & now it doesn't restart on it's own. My computer will seem normal for hours, but then it happens again. One thing i noticed was i wouldn't be able to go on any websites (even though i was still connected to the internet) right before the blue screen would appear. I don't know very much about computers. Can someone please help me?
