So just today my computer did this. I turned my pc off to save power last night, woke up in the morning went to the gym and when I got back I decided I wanted to play a game, so I booted up and it went to a black screen after the MSI logo. So I rebooted 3 more times and it did the same thing. So I left it on the black screen for 2 hours and when I came back it was on windows log in then I went to unlock the door for someone and it was black screen again. So I cleared the cmos and switched to ACHI and still the same result, also tried to boot to disk and got a black screen after the mobo logo. I'm out of ideas please help
