Alienwarw 17r4 not booting windows. Stuck on alienware logo
I was playing a game when it suddenly stuttered and had a BSOD I wasnt able to take a photo of it because it flashed too fast. After that it went into scanning and repairing then it restarted and it just stayed on the alienware logo. At first I didnt mind until 4 hours have passed and it was still there. I pressed enter and a message appeared saying "Runtime error! Program: C:\WINDOWS\system32\Logonui.exe" I dont know what I couldve done for this to happen. I would relly appreciate the help.
