Can't acess BIOS Asus X550CC

[rubendeus]

Hello!

 

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!
