I have a notebook Asus X550CC.
Some weeks ago my screen went black with the brightness working though (black screen but one can see brightness changes) - I couldn't figure out the root of the problem, since it was sudden and it works with an external monitor.
Now, I was trying to install an SSD with a caddy. I went to BIOS to change the boot order, but couldn't find my SSD - so, I accidently disabled launch CSM option hoping it would recognize it or something. After that I couldn't access BIOS anymore and I have a very slow startup with dxgkrnl.sys, wdfilter.sys and CAD.sys showing not loaded in the boot log.
I tried to:
Remove CMOS battery for 8h
Short JRST2001 and JRST2002
Access BIOS through windows 10 troubleshooting
None of the above worked for me
The laptop does not restart or shuts down correctly as it gets stuck somewhere and I have to press ON/OFF button again in order to shut it completly. The only display I can see in the external monitor, during start-up is the windows 10 loading screen (can't see the asus loading screen) and it takes more than 5 minutes to get me there (seems like a bootloop).
I hope someone may have the answer cause I'm running out of solutions
Thanks in advance, everyone!
