So, after getting immersed in a ranked game in league of legends, I really didn't want to die... And I did, I ended up raging and hitting my keyboard on my laptop, a the game started glitching out and the in game sounds started stuttering and repeating itself, however the gameplay was still fine. After the game I closed the client and it froze and stopped responding. After a while of the whole computer freezing, the BSOD appeared and re-booted my computer, and. I was to find out that there was a nice error message reading "reboot and select proper boot device". I ran a dell diagnosis and it said something about hdd not being detected bla bla and the number 7. I have tried changing primary boot etc and also removing and replacing the hdd. I don't know what to do.. Any help?
