Last Friday I was working on someone's laptop because it was running slow. I checked for any Windows Updates that it needed and installed them. It restarted and then it went to Lenovo EE Boot Optimizer for some reason? So I let it do its thing and when it was finished it came to the login page like it normally would. I typed in the password and it loaded to a black screen so I didn't see the desktop like I would before this problem occurred. So I panicked and I shut it down by pressing down the power button.
When I turned it back on it displayed a blue screen error message. It says _PAGE_FAULT_IN_NONPAGED_AREA. Then at the bottom it says STOP: 0x00000050. I am not sure what to do and why it is doing this. Would you think the virus protection may be the reason why it started acting weird in the beginning and when I performed windows update it somehow became a problem with the virus protection software uploaded on the laptop? She has avast! Just was curious because that was the last thing I did while I was working on it.
I tried starting windows normally and safe mode and I had no success. Yesterday I tried Repair your computer option and went into System Recovery Options. I tried system repair and no success. I tried system restore and system image recovery and it said I didn't have a restore point. However, when I first chose the Repair your computer option it opened up a window and I chose what country I live and then another window popped up and I saw the username. I did not recognize the first option they had so I chose the one I knew. Should I have chosen the first username option instead of the I picked and did the System Recovery Options with that? Oh and I almost forgot I also did Windows Memory Diagnostic and still on the blue screen.
It does not restart when I see the blue screen it is still. Like it doesn't move. Can someone please help me? I can't get past it even to the login page and desktop. If someone can please help, I would greatly appreciate it!
The laptop is a Lenovo B575, Windows 7 Home Premium. If that helps.
