Hi I have a msi gt780dxr gaming laptop that I've had for 3 years now. It just recently got a blue screen error message in the middle of running and hasn't started since. Now when I try to turn it on the screen stays completely black with no sound. I can hear the drivers and disc running but that's about it. Prior to this my laptop has been turning off with no errors but just at random when not pliugged in though. For example my battery would drain faster than normal and cut off when I'd expect to have more battery life. I have bought a new battery to. Someone please help me with this.
