GPU-Nvidia 940MX

Hello, the laptop responds to the switch, the matrix polarizes, but there is no image. I reprogrammed the bios with a few batches from the forum but no change.
Is it possible to switch the board to only use the graphics in the CPU?

So your mb is not even posting and you want to disable dedicated GPU. Its not going to help. Check volatge on all coils after turning on. Flash clean me bios,swap ram stick. If problem persists, move on to check allsyspwrgd is present or not.

you need to check every power supply on the boad first, so mcplslg123 is right.
