So I have a computer I am trying to fix for a friend that it currently boot looping. It is a Windows 7 Home Premium 64-bit. According to my friend it did automatic updates and then wouldn't boot after that (he says he didn't download or change anything but I don't know that I necessarily believe that). The laptop is a Lenovo G570 if that matters.
Here is what I know so far:
Blue screen says PAGE_FAULT_IN_NON_PAGED_AREA with a stop code of 0x50
Safe Mode does not work (hangs on CLASSPNP.SYS)
Startup Repair does not work (says it can't identify the problem)
System Restore points all fail with error code 0x8000ffff
I have ran chkdsk from the command prompt, that came back fine
Haven't had time to run Memtest yet, so I will update with that
SFC can't scan because it says there is a pending repair operation and I have to reboot before I can run SFC
I checked the Minidump folder but it seems like minidumps aren't being created for the bootloop BSODs
Enabled boot logging and the ntbtlog.txt only has two entries:
Loaded driver \SystemRoot\system32\DRIVERS\Esgscanner.sys
Loaded driver \??\C:\Program Files\Enigma Software Group\SpyHunter\esgiguard.sys
It looks like spyhunter was installed recently, so I'm not sure if that is what is causing the issues? I figured those drivers wouldn't be loaded for a Safe Mode boot though. Also, not quite sure how to remove that if I can't boot the computer.
I'm thinking of trying a repair install of Windows, I can't think of much else. If you guys need any other info please let me know
