Blackscreen with blinking cursor and Windows exception Win32kbase.sys

[Dacoolmike]

Guys please help I have a windows 10 laptop just recently my laptop has been having problems with blackscreen with blinking cursor and bsod error such as windows exception win32kbase.sys and bad pool caller error. I tried to run an automatic repair but it says bootres.dll is corrupt. I don't know what causing this errors whether software, hardware, third party app, microsoft giving updates that can cause corruption or even antivirus causing it (currently I have comodo firewall). I tried sfc/scannow from command prompt it says no integral violation are found and also dism/restorehealth and it finished 100% without any problems also all my drivers are even up to date and it is still causing problems. I don't want to reformat my laptop again so hopefully you guys can help me solve this problem without resulting to reformatting. By the way here the srt log file in case this become helpful. I'm also sure this cant be a momory or ram problem considering my laptop is brand new and not even a year old.

Hi Dacoolmike. :welcome:

Windows version and build? (example: v1803, b17134)
x64 or x86?
Are you using UEFI or MBR?

Try to search the bootres.dll file in your machine, using this command (launched from an elevated command prompt):

(dir c:\bootres.dll /a /s & dir d:\bootres.dll /a /s) > "%userprofile%\desktop\bootres-list.txt"

You should find the list on your desktop (in bootres-list.txt): post its content here.

And also in your efi partition (if present).


I have a bootres.dll file in C:\Windows\Boot\Resources\ and another one in the efi partition in i:\EFI\Microsoft\Boot\Resources\bootres.dll (I used diskpart to assign a letter to the efi partition).
Unfortunately they are different in their sizes…

I found other two bootres.dll files in c:\windows\winsxs\amd64_microsoft-windows-bootres_31bf3856ad364e35_10.0.17134.1_none_249d4d7aeb1b3a8e (30/09/2018 22:38, 3,717 bytes) and in c:\windows\winsxs\amd64_microsoft-windows-bootres_31bf3856ad364e35_10.0.17134.320_none_20d7b228d7f7d928 (21/09/2018 06:08, 92,672 bytes).

I'm pretty sure my windows is up to date so its v1803 which i read from a forum has a bug with bootres.dll. and its 64bit. I dont know what uefi or mbr mean and I don't know how to check it.
